actually I referred to the very first line in a notmuch-show
buffer.  I see, it's difficult to impossible to decide which
Subject to choose for the thread if there are different
Subject: headers in the files which host the Message-Id of
the first message of the thread.


But since you mentioned it there is another glitch: If one
searches for my test case like so:

from:telegraph@gmx.net AND to:telegraph@gmx.net AND subject:one

the test case shows up.

In my particular case the notmuch-search buffer shows two
lines for two matching threads one of which stands out
because its date is 1970-01-01 because I was too lazy to
provide Date: headers in the test case's messages.

In my particular case the Subject: shown on this very line
for the test case is "two".  But if I place the cursor on
this line and hit RET, the "first" of the three messages is
shown, which in my particular case happens to be the one
with Subject: "one".  Correspondingly the very first line of
this notmuch-show buffer reads "one".

Even if it's not possible to decide which of the messages is
the "right" one, I think it would be less surprising, if the
subject shown in the notmuch-search buffer would be the one
from the "first" message shown in the notmuch-show buffer.
In most/normal cases this will be the "right" one or at
least the one the user is content with.



Ciao; Gregor
