mhonarc 2.1.0 and merging replies

I wanted to put all followups to a message in a single ordered list,
instead of splitting apart the ones from References: et al. and the ones
from Subject:.

This required the following change to mhonarc, which I thought I'd pass
back to get merged into the distribution if desired.  I didn't bother
making the behavior a resource or anything, sorry.

Thanks for the great software.
