bash completion only provides revs, not paths

Hello,

currently autocompletion in 

	ukleinek@zentaur:~/gsrc/linux-2.6 git log ar<tab>

only yields "armltd/" (i.e. the prefix of some remote tracking branches) but most of the time I want it to complete to "arch/".

I don't understand that autocompletion stuff, but probably to fix that several __git_complete_revlist should be replaced by a __git_complete_revlist_or_path. The harder part is to implement the latter function. An optimal implementation would only give back paths if there is a "--" somewhere before the cursor.

Best regards Uwe
