Thanks for the cleanups here. Just looking over the patch it's clear
that I let some code into message-file.c without coercing the style into
what I would really prefer to see, (should use talloc more, should move
away from overly-abbreviated identifiers such as "hdrsofar", and
shouldn't have ambiguously named identifiers such as "header_sofar" and
"hdrsofar").

But I didn't push the change yet. The above do look like memory leak
fixes as described in the commit message.

But this part looks like an independent bug fix that needs its own
description, (and perhaps a test case?). Could you please split the
patch into two?

Thanks,
