tcsh defines the shell variable `tcsh' to be true before running your
.cshrc, so you can conditionalize the shell startup this way.  For
example, my .cshrc includes:

  if ( $?tcsh ) set prompt="[$HOST.%\!] "

[where I have already set up $HOST] because the syntax for inserting
the line numebr into the prompt is different for tcsh and csh.  I also
conditionalize the tcsh key bindings this way.
