#2964: when $duplicate_threads='no' and no threads sorting mode duplicates can't be found
I able to use the ~= pattern search only when $duplicate_threads=yes and sorting mode by threads. The first condition seems to be a bug, according to the documentation, while the second seems like a 'known fact', although not documented. It is a bug because when $duplicate_threads is 'no' duplicate messages couldn't be found. I checked this on a maildir folder. (I checked on .1.5.11, and 1.5.16 (last available version)) -- Ticket URL: <http://dev.mutt.org/trac/ticket/2964>
