A stab at better git-show completion

["Mikael Magnusson" <mikachu@xxxxxxxxx>]

I decided i want to get very confused, so i decided to try and make
git-show completion allow
completing of the form commit:path/file where the path/file part
depends on what commit you
typed. Somehow i succeeded. (the [1,-2] is for removing the trailing colon)
