FWIW, you can detect whether STDIN is a terminal using `tty':

$ tty             # returns 0
/dev/pts/6
$ tty </dev/null  # returns 1
not a tty

But there is a complication: what we really want to know is whether
STDOUT is a terminal, not STDIN.  In bash you would do `tty <&1' to test
that, but csh cannot do this, as far as I can tell.  You can use
/dev/stdout, but I think that is somewhat less portable.  That would
leave us with:

tty -s < /dev/stdout

if ( $status == 0 ) then
	set bold=`tput bold`
	set normal=`tput sgr0`
else
	set bold=
	set normal=
endif

(I am also not aware of a csh equivalent to `if COMMAND; then' without
resorting to $status.)
