Document git-init

These days, the command does a lot more than just initialise the
object database (such as setting default config-variables,
installing template hooks...), and "git init" is actually a more
sensible name nowadays.

 DESCRIPTION
 -----------
-This command creates an empty git repository - basically a `.git` directory
-with subdirectories for `objects`, `refs/heads`, `refs/tags`, and
-template files.
-An initial `HEAD` file that references the HEAD of the master branch
-is also created.
-
-If the `$GIT_DIR` environment variable is set then it specifies a path
-to use instead of `./.git` for the base of the repository.
-
-If the object storage directory is specified via the `$GIT_OBJECT_DIRECTORY`
-environment variable then the sha1 directories are created underneath -
-otherwise the default `$GIT_DIR/objects` directory is used.
-
-Running `git-init-db` in an existing repository is safe. It will not overwrite
-things that are already there. The primary reason for rerunning `git-init-db`
-is to pick up newly added templates.
-
-Note that `git-init` is the same as `git-init-db`.

+of the repository, such as installing the default hooks and
+setting the configuration variables.  The old name is retained
+because people are so used to it and many existing documents
+refer to it that way, and this will not change for some time to
+come.
