The git-completion.bash script did not implemented full, git aware,
support for completion, for git commands that operate on files within
the current working directory or the index.
For these commands, only long options completion was available.
As an example:
git add <TAB>
will suggest all files in the current working directory, including
ignored files and files that have not been modified.
Full support for completion is now implemented, for git commands where
the non-option arguments always refer to paths within the current
working directory or the index, as the follow:
* the path completion for the "git mv", "git rm" and "git ls-tree"
commands will suggest all cached files.
* the path completion for the "git add" command will suggest all
untracked and modified files. Ignored files are excluded.
* the path completion for the "git clean" command will suggest all
untracked files. Ignored files are excluded.
* the path completion for the "git commit" command will suggest all
files that have been modified from the HEAD.
For all affected commands, completion will always stop at directory
boundary. Only standard ignored files are excluded, using the
--exclude-standard option of the ls-files command.
