Yes, but some csh implementations also require

	% alias shell=/bin/sh

which is prepended to any command line which attempts to exec() a file
which fails; the alias is prepended and the exec() is tried again.

Of course, this breaks other things in the shell (sigh).  Oh well, good
riddance to csh!

I did notice, though, that you Amix folks have fixed the SVR4 csh bug
concerning changing directory two levels into a symbolic link, and
then backing out again with "cd .."  My question is, "why in the world
did csh even care?!"  (Er, rhetorical question.  One does not ask _why_
the C shell does what it does...)
