screen does not support this; its automatic titling stuff is relatively
simple.  Since you're running tcsh, you could use the postcmd alias to
achieve what you want.  (postcmd is tcsh's analog to zsh's preexec.)

I see form my notes that the tcsh invocation to get the name of the
current command into the shelltitle is

  alias postcmd 'echo -ne "^[k\!#:0^[\\"'

so this should do roughly what you want:

  alias postcmd 'echo -ne "^[k\!#:0 \!#:$^[\\"'

Now, for zsh, I might do something like this:

  preexec () {
      if [[ "$TERM" == "screen" ]]; then
          local CMD="${1[(wr)^(<*|*=*|sudo|exec|-*)]} 
          echo -n "\ek$CMD\e\\"

which pulls out the first and second non-variable, non-input redirection,
non-option elements of the command line.  (It's not terribly happy if
there isn't a second (or first, for that matter) such element.)

I got stuck on a roadtrip with nothing but _3001_ to read.  Ugh.  That was
even worse than the time I got stuck in the San Jose airport with nothing
at all to read.
