bug#54162: 29.0.50; notmuch search for nnmaildir is broken

[Jose A Ortega Ruiz]

hi,

nnmaildir servers can be configured without apparent problem in emacs 28
(pre-release branch) with notmuch as their search engine.  for instance,
if my maildirs live in ~/var/mail and i index them with notmuch, i can
use as gnus-secondary-select-methods something like:

     ((nnmaildir ""
                 (directory "~/var/mail/")
                 (gnus-search-engine gnus-search-notmuch
                                     (remove-prefix "/home/jao/var/mail/"))))

and searches work just fine.  however, in current master, all searches
simply report, very quickly, empty results, without even logging
anything (despite gnus-verbose set to 10).

i suspect this is a side-effect of the latest fixes for AW in search
results for nnml, but i don't have time to dig deeper, sorry.

cheers,
jao
