The code that tries to extract the real human name from the "From" field
is, inevitably, a set of heuristics.  We tuned them for quite a while,
and then moved on to other things.  What it is good at, therefore,
inevitably reflects the range of From: fields we were seeing at CMU
circa 1987.  It isn't surprising if what you're seeing at UVM in 1991 is
different, or that our heuristics are not adequate for all those cases.

In general, I found it a tiring and losing effort to constantly update
those heuristics, so eventually I just stopped.  Wouldn't it be nice if
there was a standard header for "Sender-Real-Name" that everyone used? 
In the absence of such a standard, though, we have heuristics.  The code
that implements the heuristics is pretty straightforward, and can be
found in ams/libs/ms/prettyn.c.  I would encourage anyone who cares
enough & has the energy to go fiddle with that file.  In a sense, you
can't really do any harm, since all you can do is alter the set of
things that show up on the caption -- it isn't like you could cause mail
to vanish or anything....
