Bug: ol-notmuch.el: calls `notmuch-show' with arbitrary search query

[Sean Whitton]

Dear maintainers,

The function `org-notmuch-follow-link' in {org,ol}-notmuch.el calls
`notmuch-show' with an arbitrary notmuch search query.  However, the
docstring for `notmuch-show' specifies that a notmuch thread ID, rather
than an arbitrary notmuch query, should be supplied to `notmuch-show'.

The effect of this is that the variable `notmuch-show-thread-id' may
contain an arbitrary search query rather than a thread ID.  That broke
some code of mine which uses that variable.

`org-notmuch-follow-link' needs to continue to accept an arbitrary query
(as notmuch thread IDs are not stable), but it should convert it to a
thread ID before passing it to `notmuch-show'.
