This function parses the displayed message to recover header
fields. It uses mailheader.el to do the actual header parsing, after
preprocessing to remove indentation. It relies on the variables
notmuch-show-message-begin-regexp, notmuch-show-header-begin-regexp,
and notmuch-show-message-end-regexp.
---
This is another patch needed for org-mode links. Really I just need
some way to get the author and subject of the current message in
notmuch-show-mode. It seems like a generally useful function,
although of course it would be more efficient to cache these headers
somewhere if the function is being invoked many times.
