The prints are clear enough.

If stop do to "edit" then it prints ... you do:
git commit --amend
git rebase --continue

If stop do to merge-conflict it prints ... you do:
git add ... (Note no commit command)
git rebase --continue

You should be getting used to it after a while, I promise you

What?!? no, why. Just empty out the message at editor and save. It will abort
any commit and do nothing. 
(For example with kwrite, ctrl-a, delete, ctrl-s, exit)

It does not matter if the commit as entered some default text for you or
not. When editor is done if file is empty (or all comments) then it will
abort and do nothing. Do not worry. The original commit is un affected.
The message is just extracted from the original commit put to a tmp file
and enter into editor. (its just a commit -c after all)
