So many people spoke for it, it's time I crash the wedding.

The function of the program would no longer be dependent on the command 
line arguments and your config, but _also_ on something as volatile as 
the index.

You would literally end up asking "did I change the index?" _everytime_ 
before you commit.

And remember, even a simple "git add" changes the index! (Why it does is 
brutally clear once you grasp the concept of the staging area.)

Worse, doing a "git commit --amend" should _not_ automatically add "-a" 
_even_ if the index matches the HEAD, since it is quite possible that you 
had a typo in the message you want to fix up. And quite possibly other 
options would not want that either.

But here's an idea: tell the user that she has to tell git-commit which 
files she wants committed. Yes! That's it. Just tell it the friggin' 
files. And if you are a lazy bum, and want to commit _all_ modified 
files, git has a nice shortcut for ya: "-a".
