This seems to actually fix the bug now, hopefully for good...although
I've said that, before...but I think I finally found the root
cause (at least, without digging into EWOC internals).
I think this may be a better default, because it allows more of
Emacs's power to be used, e.g. Occur buffers to show all messages from
a user (which needs the username displayed with each message rather
than as a header above a group of messages).
The ultimate fix for this was to send /messages the proper kind of
filter, a RoomEventFilter, rather than sending it the kind of filter
that /sync expects. This is legitimately confusing, and there's even
an issue about it:
<https://github.com/matrix-org/matrix-doc/issues/706>.
This commit fixes the problem by using the right kind of filter for
/messages.
Thanks to Michael (@t3chguy) in #matrix-dev:matrix.org, who helped me
identify the problem.
Also thanks to him for clarifying that membership events may be in
both state and timeline events in a room, so calculating a displayname
requires searching both. This commit tries to be more...comprehensive
in doing this (perhaps more than necessary, but tidying that up can be
done later if optimization is needed).

WIP: Don't insert reaction events as nodes
This seems to work well. However, the event-processing needs some
refactoring, because the logic is now spread across a few places.

Remaining issue is that reactions still insert empty events in the

WIP: And in -retro-callback
A bug now is that, every time a room's buffer is created anew, the
reactions are duplicated.

WIP: Call -room---process-events in -room--buffer
This almost seems to work, in that reactions from old timeline
events are displayed when the buffer is made...or not? It seems to
work in some cases, but not in others, like when retro-loading...
The big issue now is that the reaction events cause blank events to be
inserted into the buffer. Fixing that will require conditionally
inserting events, which probably means moving message event handling
into the defevent macro, which will require some more refactoring...

WIP: Add: Reactions
It works for newly received reactions, but after initial sync,
reactions that happened in the past are not displayed. I think it's
because the related events aren't found in the room's timeline, but I
tried to fix that, and it still doesn't work.
I'm guessing there are some assumptions that I'm making wrongly, or
something that I don't understand about how the server sends events.
We may have to save a list of certain types of events and process them
after all other events have been processed. Ugh.
The good news is that EWOC makes it pretty easy and reliable to update
messages in the buffer.
