'A...B' is a shortcut for 'A B --not $(git-merge-base --all A B)'.
This XOR-like operation is called symmetric difference in set
theory.
The symbol '...' has been chosen because it's rather similar to the
existing '..' operator and the somewhat more natural caret ('^') is
already taken.

Add get_merge_bases_clean(), a wrapper for get_merge_bases() that cleans
up after doing its work and make get_merge_bases() NOT clean up.
Single-shot programs like git-merge-base can use the dirty and fast
version.
Also move the object flags used in get_merge_bases() out of the range
defined in revision.h. This fixes the "66ae0c77...ced9456a
89719209...262a6ef7" test of the ... operator which is introduced with
the next patch.

git.c:main() relies on the value of errno being set by the last attempt to
execute the command. However, if something goes awry in handle_alias(),
that assumption is wrong. So restore errno before returning from
handle_alias().

Indexes are only needed when we are about preparing to commit. Prime them
inside commit() when we have all the info we need, and remove all the
redundant index setups.
While we are at it, make sure that index handling is correct when opening
new branches, and on initial import.

Slower connections can make git-svn look as if it's doing
nothing for a long time; leaving the user wondering if we're
actually doing anything. Now we print some file progress just
to assure the user that something is going on while they're
waiting.
Added the -q/--quiet option to users to revert to the old method
if they preferred it.

--follow-parent:
This is especially helpful when we're tracking a directory
that has been moved around within the repository, or if we
started tracking a branch and never tracked the trunk it was
descended from.
This relies on the SVN::* libraries to work. We can't
reliably parse path info from the svn command-line client
without relying on XML, so it's better just to have the SVN::*
libs installed.
This also removes oldvalue verification when calling update-ref
In SVN, branches can be deleted, and then recreated under the
same path as the original one with different ancestry
information, causing parent information to be mismatched /
misordered.
Also force the current ref, if existing, to be a parent,
regardless of whether or not it was specified.
--no-metadata:
This gets rid of the git-svn-id: lines at the end of every commit.
With this, you lose the ability to use the rebuild command. If
you ever lose your .git/svn/git-svn/.rev_db file, you won't be
able to fetch again, either. This is fine for one-shot imports.
Also fix some issues with multi-fetch --follow-parent that were
exposed while testing this. Additionally, repack checking is
simplified greatly.
git-svn log will not work on repositories using this, either.

The 'graft-branches' command can now analyze tree matches for
merge detection after commits are done, when --branch or
--branch-all-refs options are used.
We ensure that tree joins (--branch and --branch-all-refs
options) during commit time only add SVN parents that occurred
before the commit we're importing
Also fixed branch detection via merge messages, this manner of
merge detection (a la git-svnimport) is really all fuzzy, but at
least it actually works now :)
Add some new tests to go along with these fixes, too.

Tested on a plain Ubuntu Hoary installation
using subversion 1.1.1-2ubuntu3
1.1.x issues I had to deal with:
* Avoid the noisy command-line client compatibility check if we
use the libraries.
* get_log() arguments differ (now using a nice wrapper from
Junio's suggestion)
* get_file() is picky about what kind of file handles it gets,
so I ended up redirecting STDOUT. I'm probably overflushing
my file handles, but that's the safest thing to do...
* BDB kept segfaulting on me during tests, so svnadmin will use FSFS
whenever we can.
* If somebody used an expanded CVS $Id$ line inside a file, then
propsetting it to use svn:keywords will cause the original CVS
$Id$ to be retained when asked for the original file. As far as
I can see, this is a server-side issue. We won't care in the
test anymore, as long as it's not expanded by SVN, a static
CVS $Id$ line is fine.
While we're at making ourselves more compatible, avoid grep
along with the -q flag, which is GNU-specific. (grep avoidance
tip from Junio, too)

- combine_diff() took cnt (count) which is unsigned in nature but the
parameter type was declared as "int";
- find_next() took "uninteresting" parameter, which masked a static
function of the same name;
- show_parent_lno() took an unused parameter "cnt";
- show_patch_diff() used a local variable in nested inner scope with
the same name with different type, masking the one in the outer scope;
- the last loop in show_patch_diff iterated over lines so it should use
the local variable "lno"

After a clone, packfiles are read-only by default and "mv" to
replace the pack with a new one goes interactive, asking if the
user wants to replace it. If one is successfully moved and the
other is not, the pack and its idx would become out-of-sync and
corrupts the repository.
Recovering is straightforward -- it is just the matter of
finding the remaining .tmp-pack-* and make sure they are both
moved -- but we should be extra careful not to do something so
alarming to the users.

This lets you use something like this in your $GIT_DIR/config
file.
[diff]
color = auto
[diff.color]
new = blue
old = yellow
frag = reverse
When diff.color is set to "auto", colored diff is enabled when
the standard output is the terminal. Other choices are "always",
and "never". Usual boolean true/false can also be used.
The colormap entries can specify colors for the following slots:
plain - lines that appear in both old and new file (context)
meta - diff --git header and extended git diff headers
frag - @@ -n,m +l,k @@ lines (hunk header)
old - lines deleted from old file
new - lines added to new file
The following color names can be used:
normal, bold, dim, l, blink, reverse, reset,
black, red, green, yellow, blue, magenta, cyan,
white

The current behaviour strips out lines starting with a # even when fed
through stdin or -m. This is particularly bad when importing history from
another SCM (tailor 0.9.23 uses git-commit). In the best cases all lines
are stripped and the commit fails with a confusing "empty log message"
error, but in many cases the commit is done, with loss of information.
Note that it is quite peculiar to just have "#" handled as a leading
comment char here. One commonly meet CVS: or CG: or STG: as prefixes, and
using GIT: would be more robust as well as consistent with other commit
tools. However, that would break any tool relying on the # (if any).

This cleans up the use of safe_strncpy() even more. Since it has the
same semantics as strlcpy() use this name instead. Also move the
definition from inside path.c to its own file compat/strlcpy.c, and use
it conditionally at compile time, since some platforms already has
strlcpy(). It's included in the same way as compat/setenv.c.

It does not make much sense to build git whose behaviour is
different depending on the brokenness of diff implementation of
the platform because the brokenness of the patch that is applied
with the tool depends on brokenness of the diff the person who
generates the patch uses. So we do not use NO_ACCURATE_DIFF
anymore, but help people to apply patches that do not record
incomplete lines correctly with a runtime flag.

Two bugs had slipped in the "keep one index per branch during import"
patch. Both incremental imports and new branches would see an
empty tree for their initial commit. Now we cover all the relevant

preparing the actual commit, and doing it.
