[PATCH] rebase -i: make post-rewrite work for 'edit'

[Thomas Rast <trast@student.ethz.ch>]

The post-rewrite support, in the form of the call to
'record_in_rewritten', was hidden in the arm where we have to record a
new commit for the user.  This meant that it was never invoked in the
case where the user has already amended the commit by herself.

[The test is designed to exercise both arms of the 'if' in question.]

Furthermore, recording the stopped-sha (the SHA1 of the commit before
the editing) suffered from a cut&paste error from die_with_patch and
used the wrong variable, hence it never recorded anything.

Noticed by Junio.

No need for question marks, this is not only a bug but also squarely
in the wtf-was-I-smoking department ;-)

I changed the test slightly from what you describe, to make it go
through both code paths (as indicated in the bracketed remark).
