\... csh/tcsh doesn't support multi-line aliases using
\"if", so there's no way to do the "else" part in an alias.

Is that a fact?

	% alias z 'if (! -e \!^) set status=1 && echo yes || echo no'
	% z /
	yes
	% z /etc/foobar
	no

Allright, it doesn't contain the word "else" and it's ugly, but don't you
write off our beloved csh that fast, sonny! :-)
