A very lovely change, Jesse! Thanks for this (which is now pushed). And
again, thanks to Sebastian for guiding the patch through the file
renaming.

There is one minor issue with this patch which is that viewing an
identical thread more than once will bring up a new buffer rather than
re-using the existing buffer. But of course, we *want* a separate buffer
if the thread-ID is different but the (abbreviated) subject just happens
to match. So there would have to be something clever to do the right
thing here. I'm not making this minor regression block the patch, since
it's so nice otherwise.

That last paragraph above is good guidance for understanding the patch,
but not useful as part of the permanent commit history. So I removed it
before pushing the commit. In the future, you can put text like that
*after* the "---" just below your Signed-off-by and then "git am" will
automatically ignore it.
