One reason why is because you are using "-m foo" (a very
non-descriptive commit message that would not help anybody
including yourself in the future).  Try the above without giving
such a bogus error message with "-m" to commit, but instead let
it spawn your editor --- you would be doing that in real-life
when you are doing anything nontrivial.  Then notice what
appears on the file list of "Changed but not updated" section.

A single liner "-m" is handy for "Oops, typofix in foo.c" kind
of commit, but in such a case you literally would be changing
only the typofix and won't have "edit foo.c; git add foo.c; edit
foo.c; git commit" sequence anyway.

I think Linus explained quite well to correct your doubts in
your original message, and I do not have anything to add.
