I released git 184.108.40.206 with Bash completion for Ubuntu 10.10 today. To use my repository follow the instructions on the page Git Packages for Ubuntu.
It took a little bit longer to release as I was writing a patch fixing bash completion. The patch is integrated in my package of git for Ubuntu 10.04.
A little more detailed explanation of the bash completion patch.
If you use bash as your shell, you can press
For example if you type:
git log --pretty=
it resulted in a list of files from the current directory.
With the patch in this package of git it results in
email full medium raw format: fuller oneline short
just as you would expect.
It turned out that the completion script was broken with Bash 4, it didn’t just effect the above example but a whole array of other git commands as well.
