Subject-only thread order

[Andrew Johnson <anj@aps.anl.gov>]

Can anyone explain the order in which the following messages appear in a
thread index created by MHonArc 2.4.7 from an old mail archive which
unfortunately had all the cross-reference headers removed so has to be
threaded by Subject.  My rcfile contains both <TSort> and <Sort>, but not
<MultiPg>.

The original question (Msg 00007) occurs at the lowest index number and
the earliest time, but some other message has been picked as the top of
the thread.  We have several archives like this without the
cross-references, and the current order of some threads is rather
confusing.  Is this a bug, a feature, or something that I haven't
configured properly?

TIA,
