Done.

Perhaps a useful rule of thumb is that functions referencing
buffer-local vars should be interactive?  I'm not sure that follows for
all cases, but I certainly agree that global and buffer-local vars
should probably not be referenced gratuitously, and pure functions are
generally good.

Calling what I have in mind "plans" may be a stretch.  ;-) I'm not sure
this function is useful for notmuch-tree as written.  At minimum, I
would expect a shared function to have a different name.  But I think
you're right that there is probably opportunity for code sharing,
especially if notmuch grows more complex features with respect to
searching vs. expanding messages in threads.

Look for a v4 of this patch soon.  I appreciate your review so far.
