git bash completion for checkout returns only tags

[Richard Laager]

The bash completion code for git returns only tags. As a result, substrings that match both tags and filenames will only result in the tag choices being offered, to the exclusion of the filenames. (If the substring matches only filenames, then bash itself will offer the filename completions.)

This is really annoying when you're using git-buildpackage, as you'll have tags of the form debian/... as well as files in a debian/ directory. The bash completion code for git should also return filenames for `git checkout <TAB>`.

Steps to reproduce:
mkdir foo
cd foo
git init
mkdir debian
touch debian/control
git add debian/control
git commit -am "blah"
git tag debian/1.0.0-1
git checkout deb<TAB>

Expected result:
debian/1.0.0-1 debian/control
$ git checkout deb

Actual result:
$ git checkout debian/1.0.0-1

Behavior confirmed on Ubuntu 11.10, git 1.7.5.4-1 using steps to reproduce from OP.

Bug #853081 is similar: the tags also have preference over the files, but for the git log and git diff commands.

Probably due to the same error in the bash completion script?
