[neomutt-users] server-side ('l =b <pattern>') search claims "Success", yet index not limited

[Brian Parent]

Using ~b to for body searches correctly displays the limited matching set of messages in the index,
but using =b for the same search string results in displaying all messages in the index.

Using debug level 5, the search claims "Success".
Indeed, when the search fails, the index list is empty, as expected.
So, the failure doesn't appear to be the search itself, but in the resulting index display.

The problem exists in NeoMutt 20200424, but not in NeoMutt 20180716.

I installed 20200424 using MacPorts "port install neomutt +gdbm +sasl"

After noticing the failure, I restored the previous (20180716) version, and the problem went away.

Here's the relevant debug output ('l =b fileset'):

The mutt_progress_update() lines show evidence that all messages are getting listed in the index, though the search should have limited the index items to one or two messages.

My googlefu didn't turn up anyone else complaining about this, and I checked the archives for this list by reviewing subjects over the past 16 months (too bad the archives aren't searchable), with no luck.  At this point, it seems like a bug, but I thought I'd check on this users list first.

For now, I can continue to use the older version, but it would be nice to be able to get more current.
