The git-completion.bash script did not implemented full, git aware,
support to complete paths, for git commands that operate on files within
the current working directory or the index.
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.
Support path completion, 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 rm" and "git ls-files"
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 mv" command will suggest all cached
files when expanding the first argument, and all untracked and cached
files for subsequent arguments. In the latter case, empty directories
are included and ignored files are excluded.
* the path completion for the "git commit" command will suggest all
files that have been modified from the HEAD, if HEAD exists, otherwise
it will suggest all cached files.
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.

Changes from version 3:
* Fixed quoting issues
* Fixed default parameters handling
* Fixed a typo in the commit message: the affected command was ls-files,
not ls-tree.
* Fixed incorrect behavior when expanding a path in "git commit"
command, for a newly created repository (when HEAD does not
exists).
* Make sure to always execute git commands with stderr redirected to
/dev/null.
* Improved path completion for the git mv command.
This required a small refactorization of the __git_index_files
function, in order to support multiple options for ls-files.
