error for tcsh users in FC2T3

[David Jansen <jansen strw leidenuniv nl>]

Since a couple of days, users who have tcsh as their shell get an error
on login:
MAIL=/var/spool/mail/jansen: Command not found.

And indeed, the last line of /etc/csh.cshrc is:
MAIL="/var/spool/mail/$USER"

The error was not present directly after installing FC2Test3, it came
with an update:

$ rpm -qf /etc/csh.cshrc
setup-2.5.32-1
$ ls -l  /etc/csh.cshrc
-rw-r--r--  1 root root 592 May  5 05:52 /etc/csh.cshrc
