ptrace man page lies on many systems

[Steven M. Kramer]

The ptrace man page says that when reading the U area to have an
even Addr.  Well, that should really be integer alligned on many UNIX
systems, not just even.  The even req only works for 16 bit ints.
For 32 bits, it's a div 4 decision.  Also, it specifies that the
Addr must be less that 512.

	How old is this man page?  It's on 4.2bsd and really should
be updated.  I'ts probably unchanged in most UNIXs.  After all, how many
people really use this call except for me??:-)??    (The man page compares
with an original V7 man page I had around!)
