Short walkthrough:
  - create a small message in the database (add_message)
  - set message-hidden-headers to nil so that we can verify them
  - set notmuch-fcc-dirs to nil to avoid including the fcc-header
  - get the message we just created (notmuch-show)
  - create a forwarding message (forwarding the current one)
  - compare the headers to the expected output
  - run the send hooks to emulate sending

The double run-hooks lines is an error; only the second one is needed.

Yes.  This seems to be common in the emacs code for notmuch, so I did
not untabify.

The test was only supposed to check that the forwarded tag was properly
added when forwarding.  If other tags are added elsewhere in future
code, this is not really an error and should not be flagged by the test,
should it?
