Yes, I can reproduce this. "git bisect" tells me it was introduced by v1.7.6-rc0~65^2~4 (completion: remove unnecessary _get_comp_words_by_ref() invocations, 2011-04-28). Since then, Felipe has done work to make reusing subcommand completion easy again, so you can do

	__git_complete gtlg _git_log

One complication: on some systems, including Ubuntu 13.04, git's bash completion script is installed to

	/usr/share/bash-completion/completions/git

and sourced on the fly when completing commands starting with "git" instead of right away from /etc/bash_completion. On these systems, the "__git_complete" function would not be usable right away from your .bashrc file. I think we should fix this, for example by moving the function to a separate

	$(git --exec-path)/git-bashrc-functions

library.

Thanks for reporting, Jonathan
