[PATCH] rebase -i: abort cleanly if the editor fails to launch

["Björn Gustavsson" <bgustavsson@gmail.com>]

If the user's configured editor is emacsclient, the editor
will fail to launch if emacs is not running and the git
command that tried to lanuch the editor will abort. For most
commands, all you have to do is to start emacs and repeat
the command.

The "git rebase -i" command, however, aborts without cleaning
the "$GIT_DIR/rebase-merge" directory if it fails to launch the
editor, so you'll need to do "git rebase --abort" before
repeating the rebase command.

Change "git rebase -i" to terminate using "die_abort" (instead of
with "die") if the initial launch of the editor fails.
