   Here's a small patch for xterm.

   Using tcsh, I set re-set the title of xterm before each shell prompt,
   so that it states my current working directory.  This ensures that my
   title is up to date, no matter where I am, or what I'm doing.

This may be a nit, but what is wrong with cwdcmd in tcsh?  It does
what you want with a minimum of fuss and without messing with the
xterm source.  When I ran tcsh I used the following for my xterms and
never got that annoying flicker.  (Note that the ^[ are real escapes,
and the ^G and ^A are real control characters.)

#
# Prompting information for tcsh.
#
if ($?DISPLAY) then             # X Windows Prompt
        alias cwdcmd 'echo -n "^[]0;"{$HOST}":$cwd^G"'
        echo -n "^[]0;"{$HOST}":$cwd^G"
        set prompt="%h> "
# Suntools Prompting
else if ($?WINDOW_PARENT || ($TERM == "sun" && `tty` != "/dev/console")) then
        alias cwdcmd 'echo -n "^[]l"{$HOST}": $cwd^[\^A"'
        echo -n ^[\]l"$HOST": $cwd^[\\
        set prompt="%h> "
else                            # Everything else
        set prompt={$HOST}":%~> "
endif
