Csh question: Doing cd .. from a symbolically linked directory

[Maarten Litmaath]

Here's a slight improvement; check the output of `cd /'; furthermore
you won't get into trouble if you accidentally type `cd foo/ bar' or
if there is a subdirectory `0' and you type `cd0'.

alias	cd	'set tmp=(\!*); eval _cd_$#tmp $cwd \!*//. ../ ~; echo $cwd'
alias	_cd_0	'chdir \!$'
alias	_cd_1	'if (x\!:2 !~ x../*) set status=1'\
		'&& eval _cd_x /\!^:h \!:2-:s-../--'\
		'|| chdir \!:2:h'
alias	_cd_x	'if (x\!:2 !~ x../*) set status=1'\
		'&& eval _cd_x /\!^:h \!:2*:s-../--'\
		'|| chdir \!^/\!:2:h'
alias	pwd	'echo $cwd'
