This was a bug that was introduced in copying the indexing code over
into notmuch-show.c. When indexing, we want to ignore the signature,
(it has no interesting terms). But when presenting the message, it's
important to present the signature to the user.
(And would be even better if we presented whether or not the signature
is good.)
The advantage here is that we actually get the necessary folding of
long headers, (particularly the References header, but also things
like Subject). This also gives us parsed recipient addresses so that
we can easily elide the sender's address(es) from the recipient list
(just as soon as we have a configured value for the recipient's
address(es)).

Keith wrote all the code here against notmuch before notmuch.c was
split up into multiple files. So I've pushed the code around in
various ways to match the new code structure, but have generally tried
to avoid making any changes to the behavior of the code.
I did fix one bug---a missing call to g_mime_stream_file_set_owner in
show_part which would cause "notmuch show" to go off into the weeds
when trying to show multiple messages, (since the first stream would
fclose stdout).
