Ah, but csh includes the environment variable $cwd.  This makes setting
foo unnecessary.  It seems to me that you could remove the part that says:

	set foo=`pwd`

and replace every occurrence of $foo with $cwd.

I haven't actually tested these examples so I hope I didn't just stick
my foot in my mouth, but I did do something like this once so I'm pretty
sure it'll work.  I only make this suggestion because if your system is
running slow, every extra binary you run (in this case 'pwd') will just
be that much more irritation.
