Check your $LESSOPEN environment variable. The default value for me is
"|/usr/bin/lesspipe.sh %s". If you look at /usr/bin/lesspipe.sh, it's a
(bourne) shell script. How or why this would end up executing a .cshrc,
I don't know, but that LESSOPEN thing has caused more pain for me than
it's helped (it never seems to work from an ssh terminal).

At any rate, many utilities will end up having this behaviour (I suspect
you may get the same thing trying to use /usr/bin/which). You may want
to consider moving that stuff out of your .cshrc and into your .login
file, so it only gets executed on login shells.
