Provide an option to make thread summaries keep initial subject

2012-09-25 Thread Olivier Berger
Hi.

Whenever a participant changes the subject in the middle of a thread,
the summary reported by notmuch search will change.

However, the result is that some mails tend to "disappear" from search
results, when (bad) participants reply instead of composing a new mail,
and change a subject (see
http://bugs.debian.org/cgi-bin/bugreport.cgi?bug=688699 for more details
on that problem, and a discussion). Of course, they're still there, but
their subject being masked, one may then grep or C-s for a particular
subject and miss them.

I think it would be interesting to allow notmuch to potentially keep the
original subject and not the most recent one for the thread summaries.

What do you think ?

Best regards,

I think this would be fantastic.  I've proposed unconditionally
showing the earliest subject before and it seems that people who
correspond mostly with those who have good threading etiquette would
prefer this change, but those who correspond with more people who use
'reply' like an address book prefer the current behavior.

Another option, which I'd like to experiment with but haven't found
the time, is to show *all* distinct subjects for matched messages in a
thread (modulo "Re:", etc) in the summary buffer, probably on multiple
lines.  Since most threads only have a single unique subject, they
would appear just as they do now, but it would be clear when someone
(or something, like git) changed the subject mid-thread.  This
approach would be far more robust while retaining good usability, but
it would require more code than just changing our subject-picking
heuristic.
