Reading my message (including the last 5 words of the sentence you're
quoting) would have told you that ;-).

In other systems, commit commits _exactly_ the content of files on
disk. And most people seem happy with that.

Does this mean that the normal way to use "commit" is to use "-a"?

Well, with those kind of arguments, I could have my web browser not do
DNS resolution for me, because it would make it clear that a separate
step from HTTP request is involved. Still, this low-level thing brings
no benefit to the user, and I know no web browser forcing the user to
make this distinction.

You don't necessarily see your error from the file list:

% vi foo.c
% git add foo.c
% vi foo.c
% git commit -m foo
[...]
 create mode 100644 foo.c
%

This commited the old content of foo.c, while I hardly see any
scenario where this is the expected behavior.

Then, being able to repare the error if I made it is interesting, but
I don't get the reason why the error could not just be avoided.

Well, indeed, I just found a thread talking about this:

  http://lists-archives.org/git/196050-making-git-commit-to-mean-git-commit-a.html

I'll go through it, I might understand better after that ;-).

Thanks,
