If after a failed "exec" instruction there are staged changes, before
this patch, rebase --continue fails with this message, which is obviously
wrong:
.../git-rebase--interactive: line 774: .../.git/rebase-merge/author-script: No such file or directory
We could try auto-amending HEAD, but this goes against the logic of
.git/rebase-merge/author-script (see also the testcase 'auto-amend only
edited commits after "edit"' in t3404-rebase-interactive.sh) to
auto-amend something the user hasn't explicitely asked to edit.
Instead of doing anything automatically, detect the situation and give a
clean error message. While we're there, also clarify the error message in
case '. "$author_script"' fails, which now corresponds to really weird
senario where the author script exists but can't be read.

Here's my attempt at a patch. After noticing the existance of a test
'auto-amend only edited commits after "edit"', I'm convinced that
auto-amending is not the right thing here.
