pstat.c fixes -- you asked for it!
>From cak Tue Feb 2 20:58:48 1982
To: csvax.4bsd-bugs@berkeley
Subject: pstat.c fixes

The following diffs show changes made to allow pstat to operate
properly with post-mortem core dumps. Basically, addresses
were not having the high order bit properly cleared when dealing
with dumps.

It also fixes a recently reported bug about the addresses the -f
option reports.

Please note also that the documentation does not mention the -k
flag which is expected when dealing with core dumps.
