vi bug(feature?)

[Mark Plotnick]

Don't put any commands that may cause output (like tset or clear) in
your .cshrc file; place them in your .login file instead.

Also, in your .cshrc, make sure that any csh variables that may cause
output (such as prompt, mail, or time) are only set if the csh
is an interactive one, e.g.

if ($?prompt) then
   set time=(10 "%Uu %Ss %E %P %Xktext+%Dkdata %Ireads %Owrites %Fpf %Wswaps")
   set prompt="`hostname | sed s/tempo-//`% "
endif
