Of course, some sites control when some users can log in by adjusting
the shell. Other sites want certain users to log in only to non-shell
top-level programs. Some user I.D.s should NEVER be given a standard
shell. If one of those sites ever had a (hopefully) temporary problem
with a non-standard shell, your "fix" opens a potential security window...
