Unfortunately the headers you can use there seem to be hardcoded at the
moment in notmuch-show.c:

In order to adress this, I guess one would have to either output all
headers in notmuch show, which leaves it to the client to choose which
headers are wanted (which sounds like a good choice to me, since this is
essentially a UI preference) or add a field to the config file that
specifies additional headers to be included here.
