Ok.  I was wrong ... It can be done.  For some reason AT&T took a short-cut
and only displayed the u_comm string in the user block that only contains
the first argument.  The real way of doing it and really the "-f"
option of the ps(1) should do this.  But as usual...

A few people mentioned the way of doing it is to look up the user's stack
space in memory and read back the arguments from the "argv-block".  Likewise
you could also print the environment (like Bezerkley BSD UNIX does)...  If
anyone cares to do this before I hack it myself, by all means.  

Of course the argv can be changed easily by a program giving you erroneous
results, the user.u_comm cannot be changed [as easily :-), I learned never
to say never]...
