Missed again, thanks.
I hope this is really the last one!

Yes, $1 is always set internally (but I will check again)
Probably there are better solutions.

What is the reason?
Coding style?

Umh, I just checked this case.

  0) git init test
  1) Added a README file with "Hello World.", and committed.
  2) Modified the README file with "Hello World!" and executed
     git add README
  3) Modified the README file with "Hello World." (the original content)
  4) $ git diff HEAD:README README
     $ git diff-index --name-only HEAD
     README

     git commit <TAB> shows the README file.

If I understand correctly the documentation of diff-index, it will
always compare the content of the index with HEAD.
If --cached is specified, it will ignore the stat state of the file on disk.

It have considered it.

The problem is that the output of "git status --porcelain" is not
trivial to parse.

Yes, it is affected; I missed it, thanks.
It should count only non-option arguments.

Thanks for your review.
