Subject: [PATCH 2/4] emacs: repurpose notmuch-show-archive-thread-internal
	function for general thread tagging

Precedence: list

Instead of having a function that is only used for archiving a thread,
we instead make it useful for any tagging operation.  The new
function, notmuch-show-tag-thread-internal, now takes two more
arguments, for the "sign" of the tagging operation ("-" or "+"), and
the tag to be added or removed.  This will allow this function to be
used for any generic thread tagging operation.

The higher level functions that call this function are modified
accordingly.
