git: hash autocomplete

Is there any chance to configure git to autocomplete the hashes when pressing TAB?

Edit:

Please note that this question is not about autocomplete, but about hash autocomplete. See my comment to VonC's answer.

Sorry, I'm no bash expert. But I just tried to compile something like it for the csh family and this should be easy to transform into a bash completion script for those who know bash.

The command line I'm using to get useful, recent commit hashes is similar to:

(git branch | cut -c3-) ; (git branch | cut -c3- | xargs -ibranch git log -n 100 --pretty=format:%+H branch | sort -u)

This line works for both: bash and csh.

Basically it is the concatenation of the branch names:

git branch | cut -c3-

and the last (with n being 100) commit names (=full hash numbers)

git branch | cut -c3- | xargs -ibranch git log -n 100 --pretty=format:%+H branch | sort -u

The full autocompletion statement for csh is then like this

#
# tcsh completion for Git
#
# Taken from: https://gist.github.com/1663989
# and from: https://gtirtha.wordpress.com/2010/05/14/git-autocomplete/
# extended and merged them into what I (Ingo Schmiegel) like

set _git_commands = (add am cherry-pick commit branch format-patch ls-files help remote merge pull push amend grep rebase reset revert bisect diff difftool blame log checkout fetch stash status wdiff config)
set _git_aliase = `git config --get-regexp 'alias.*' | sed -e 's,alias.,,' | cut -d' ' -f1`

complete git "p/1/($_git_commands $_git_aliase)/" \
  "n/help/($_git_commands $_git_aliase)/" \
  'n/add/`git status --porcelain|cut -c4-|xargs echo`/' \
  'n/br/`git branch|cut -c 3-`/' 'N/br/`git branch|cut -c 3-`/' \
  'n/branch/`git branch|cut -c 3-`/' 'N/branch/`git branch|cut -c 3-`/' \
  'n/cb/`git branch|cut -c 3-`/' \
  'n/cherry-pick/`(git branch|cut -c3-);(git branch|cut -c3-|xargs -ibranch git log -n 100 --pretty=format:%+h branch|sort -u)`/' \

  'n/config/(--global --get-regexp --list)/' \
