+ * Porcelain commands like "git reset" did not distinguish deletions

+ situation.

+ * "git cherry-pick $commit" (not a range) created an unnecessary
+ sequencer state and interfered with valid workflow to use the

+ option.
+
+ * "fast-import" did not correctly update an existing notes tree,
+ possibly corrupting the fan-out.
+
+ * "git fetch-pack" accepted unqualified refs that do not begin with
+ refs/ by mistake and compensated it by matching the refspec with
+ tail-match, which was doubly wrong. This broke fetching from a
+ repository with a funny named ref "refs/foo/refs/heads/master" and a
+ 'master' branch with "git fetch-pack refs/heads/master", as the
+ command incorrectly considered the former a "match".
+
+ * "git log --follow" did not honor the rename threshold score given
+ with the -M option (e.g. "-M50%").
+
+ * "git mv" gave suboptimal error/warning messages when it overwrites

+=========

+NAME
+----
+git-p4 - Import from and submit to Perforce repositories
+
+
+SYNOPSIS
+--------
+[verse]
+'git p4 clone' [<sync options>] [<clone options>] <p4 depot path>...
+'git p4 sync' [<sync options>] [<p4 depot path>...]
+'git p4 rebase'
+'git p4 submit' [<submit options>] [<master branch name>]
+
+
+DESCRIPTION
+-----------
+This command provides a way to interact with p4 repositories
+using git.
+
+Create a new git repository from an existing p4 repository using
+'git p4 clone', giving it one or more p4 depot paths. Incorporate
+new commits from p4 changes with 'git p4 sync'. The 'sync' command
+is also used to include new branches from other p4 depot paths.
+Submit git changes back to p4 using 'git p4 submit'. The command
+'git p4 rebase' does a sync plus rebases the current branch onto
+the updated p4 remote branch.
+
+
+EXAMPLE
+-------
+* Create an alias for 'git p4', using the full path to the 'git-p4'
+ script if needed:
++
+------------
+$ git config --global alias.p4 '!git-p4'
+------------
+
+* Clone a repository:
++
+------------
+$ git p4 clone //depot/path/project
+------------
+
+* Do some work in the newly created git repository:
++
+------------
+$ cd project
+$ vi foo.h
+$ git commit -a -m "edited foo.h"
+------------
+
+* Update the git repository with recent changes from p4, rebasing your
+ work on top:
++
+------------
+$ git p4 rebase
+------------
+
+* Submit your commits back to p4:
++
+------------
+$ git p4 submit
+------------
+
+
+COMMANDS
+--------
+
+Clone
+~~~~~
+Generally, 'git p4 clone' is used to create a new git directory
+from an existing p4 repository:
+------------
+$ git p4 clone //depot/path/project
+------------
+This:
+
+1. Creates an empty git repository in a subdirectory called 'project'.
++
+2. Imports the full contents of the head revision from the given p4
+depot path into a single commit in the git branch 'refs/remotes/p4/master'.
++
+3. Creates a local branch, 'master' from this remote and checks it out.
+
+To reproduce the entire p4 history in git, use the '@all' modifier on
+the depot path:
+------------
+$ git p4 clone //depot/path/project@all
+------------
+
+
+Sync
+~~~~
+As development continues in the p4 repository, those changes can
+be included in the git repository using:
+------------
+$ git p4 sync
+------------
+This command finds new changes in p4 and imports them as git commits.
+
+P4 repositories can be added to an existing git repository using
+'git p4 sync' too:
+------------
+$ mkdir repo-git
+$ cd repo-git
+$ git init
+$ git p4 sync //path/in/your/perforce/depot
+------------
+This imports the specified depot into
+'refs/remotes/p4/master' in an existing git repository. The
+'--branch' option can be used to specify a different branch to
+be used for the p4 content.
+
+If a git repository includes branches 'refs/remotes/origin/p4', these
+will be fetched and consulted first during a 'git p4 sync'. Since
+importing directly from p4 is considerably slower than pulling changes
+from a git remote, this can be useful in a multi-developer environment.
+
+
+Rebase
+~~~~~~
+A common working pattern is to fetch the latest changes from the p4 depot
+and merge them with local uncommitted changes. Often, the p4 repository
+is the ultimate location for all code, thus a rebase workflow makes
+sense. This command does 'git p4 sync' followed by 'git rebase' to move
+local commits on top of updated p4 changes.
+------------
+$ git p4 rebase
+------------
+
+
+Submit
+~~~~~~
+Submitting changes from a git repository back to the p4 repository
+requires a separate p4 client workspace. This should be specified
+using the 'P4CLIENT' environment variable or the git configuration
+variable 'git-p4.client'. The p4 client must exist, but the client root
+will be created and populated if it does not already exist.
+
+To submit all changes that are in the current git branch but not in
+the 'p4/master' branch, use:
+------------
+$ git p4 submit
+------------
+
+To specify a branch other than the current one, use:
+------------
+$ git p4 submit topicbranch
+------------
+
+The upstream reference is generally 'refs/remotes/p4/master', but can
+be overridden using the '--origin=' command-line option.
+
+The p4 changes will be created as the user invoking 'git p4 submit'. The
+'--preserve-user' option will cause ownership to be modified
+according to the author of the git commit. This option requires admin
+privileges in p4, which can be granted using 'p4 protect'.
+
+
+OPTIONS
+-------
+
+General options
+~~~~~~~~~~~~~~~
+All commands except clone accept this option.
+
+--git-dir <dir>::
+ Set the 'GIT_DIR' environment variable. See linkgit:git[1].
+
+Sync options
+~~~~~~~~~~~~
+These options can be used in the initial 'clone' as well as in
+subsequent 'sync' operations.
+
+--branch <branch>::
+ Import changes into given branch. If the branch starts with
+ 'refs/', it will be used as is, otherwise the path 'refs/heads/'
+ will be prepended. The default branch is 'master'. If used
+ with an initial clone, no HEAD will be checked out.
++
+This example imports a new remote "p4/proj2" into an existing
+git repository:
+----
+ $ git init
+ $ git p4 sync --branch=refs/remotes/p4/proj2 //depot/proj2
+----
+
+--detect-branches::
+ Use the branch detection algorithm to find new paths in p4. It is
+ documented below in "BRANCH DETECTION".
+
+--changesfile <file>::
+ Import exactly the p4 change numbers listed in 'file', one per
+ line. Normally, 'git p4' inspects the current p4 repository
+ state and detects the changes it should import.
+
+--silent::
+ Do not print any progress information.
+
+--verbose::
+ Provide more progress information.
+
+--detect-labels::
+ Query p4 for labels associated with the depot paths, and add
+ them as tags in git.
+
+--import-local::
+ By default, p4 branches are stored in 'refs/remotes/p4/',
+ where they will be treated as remote-tracking branches by
+ linkgit:git-branch[1] and other commands. This option instead
+ puts p4 branches in 'refs/heads/p4/'. Note that future
+ sync operations must specify '--import-local' as well so that
+ they can find the p4 branches in refs/heads.
+
+--max-changes <n>::
+ Limit the number of imported changes to 'n'. Useful to
+ limit the amount of history when using the '@all' p4 revision
+ specifier.
+
+--keep-path::
+ The mapping of file names from the p4 depot path to git, by
+ default, involves removing the entire depot path. With this
+ option, the full p4 depot path is retained in git. For example,
+ path '//depot/main/foo/bar.c', when imported from
+ '//depot/main/', becomes 'foo/bar.c'. With '--keep-path', the
+ git path is instead 'depot/main/foo/bar.c'.
+
+--use-client-spec::
+ Use a client spec to find the list of interesting files in p4.
+ See the "CLIENT SPEC" section below.
+
+Clone options
+~~~~~~~~~~~~~
+These options can be used in an initial 'clone', along with the 'sync'
+options described above.
+
+--destination <directory>::
+ Where to create the git repository. If not provided, the last
+ component in the p4 depot path is used to create a new
+ directory.
+
+--bare::
+ Perform a bare clone. See linkgit:git-clone[1].
+
+-/ <path>::
+ Exclude selected depot paths when cloning.
+
+Submit options
+~~~~~~~~~~~~~~
+These options can be used to modify 'git p4 submit' behavior.
+
+--verbose::
+ Provide more progress information.
+
+--origin <commit>::
+ Upstream location from which commits are identified to submit to
+ p4. By default, this is the most recent p4 commit reachable
+ from 'HEAD'.
+
+-M[<n>]::
+ Detect renames. See linkgit:git-diff[1]. Renames will be
+ represented in p4 using explicit 'move' operations. There
+ is no corresponding option to detect copies, but there are
+ variables for both moves and copies.
+
+--preserve-user::
+ Re-author p4 changes before submitting to p4. This option
+ requires p4 admin privileges.
+
+
+DEPOT PATH SYNTAX
+-----------------
+The p4 depot path argument to 'git p4 sync' and 'git p4 clone' can
+be one or more space-separated p4 depot paths, with an optional
+p4 revision specifier on the end:
+
+"//depot/my/project"::
+ Import one commit with all files in the '#head' change under that tree.
+
+"//depot/my/project@all"::
+ Import one commit for each change in the history of that depot path.
+
+"//depot/my/project@1,6"::
+ Import only changes 1 through 6.
+
+"//depot/proj1@all //depot/proj2@all"::
+ Import all changes from both named depot paths into a single
+ repository. Only files below these directories are included.
+ There is not a subdirectory in git for each "proj1" and "proj2".
+ You must use the '--destination' option when specifying more
+ than one depot path. The revision specifier must be specified
+ identically on each depot path. If there are files in the
+ depot paths with the same name, the path with the most recently
+ updated version of the file is the one that appears in git.
+
+See 'p4 help revisions' for the full syntax of p4 revision specifiers.
+
+
+CLIENT SPEC
+-----------
+The p4 client specification is maintained with the 'p4 client' command
+and contains among other fields, a View that specifies how the depot
+is mapped into the client repository. Git-p4 can consult the client
+spec when given the '--use-client-spec' option or useClientSpec
+variable.
+
+The full syntax for a p4 view is documented in 'p4 help views'. Git-p4
+knows only a subset of the view syntax. It understands multi-line
+mappings, overlays with '+', exclusions with '-' and double-quotes
+around whitespace. Of the possible wildcards, git-p4 only handles
+'...', and only when it is at the end of the path. Git-p4 will complain
+if it encounters an unhandled wildcard.
+
+Bugs in the implementation of overlap mappings exist. If multiple depot
+paths map through overlays to the same location in the repository,
+git-p4 can choose the wrong one. This is hard to solve without
+dedicating a client spec just for git-p4.
+
+The name of the client can be given to git-p4 in multiple ways. The
+variable 'git-p4.client' takes precedence if it exists. Otherwise,
+normal p4 mechanisms of determining the client are used: environment
+variable P4CLIENT, a file referenced by P4CONFIG, or the local host name.
+
+
+BRANCH DETECTION
+----------------
+P4 does not have the same concept of a branch as git. Instead,
+p4 organizes its content as a directory tree, where by convention
+different logical branches are in different locations in the tree.
+The 'p4 branch' command is used to maintain mappings between
+different areas in the tree, and indicate related content. 'git p4'
+can use these mappings to determine branch relationships.
+
+If you have a repository where all the branches of interest exist as
+subdirectories of a single depot path, you ca
