Yes, you're right. I haven't wrapped my brain completely around those
mixed cases yet (changes in index + pathspec argument). My aim is that

"git commit <addoptions> <commitoptions> [<pathspec>]"

would be equivalent to (the atomic version of)

"git add <addoptions> [<pathspec>] && git commit <commitoptions>"

and that is difficult because currently, pathspecs are "limiting" for
commit and "additive" for add without -u. I mean, I don't want to break
anything, at least not before 1.8.0..
