I applied the  patch set and it solves the problem for the first
thread shown in id:87fu05p2iu.fsf at len.workgroup
For me this fixes the more important issue of the two.


It does not fix the ordering in the second example:

I have to admit, this is not one thread if one accounts for
threads only with respect to References -headers. 

But even if it's two threads we have two level 1 emails (1, 2) and
I would expect the level 1 emails to be sorted according to
date, the whole tree of sibling emails to every level 1 email
behind and indented relative to it's level 1 email:

2
  2a
1

This is, what mutt does.



Thanks for your efforts, it's much easier now to follow email
discussions.

Ciao; Gregor
