I'm using egg (emacs got git) as git interface in emacs. Whenever I try to achieve a commit --amend, I receive a "GIT-COMMIT-AMEND> Aborting commit due to empty commit message".

This is what i do:

C-u C-x v c

Then the commit buffer appears, with the message of my previous commit.

Then upon C-c C-c I get the message stated above: empty commit message.

I think I've had this behaviour with regular commits (as in not amend) before, but can't remember or find how I solved it.

I tried editing the message (adding a space somewhere). No work.

I tried saving the buffer before committing, that wouldn't work either (since C-c C-c is not active in another buffer than the commit buffer).

Any clue?
