Can I force tcsh to say "previous command returned empty stdout" or
something? I often cut and paste shell output for my cow-orkers, and
it's crucial to note when a command returns nothing.

Currently, I insert the information manually:

ls | fgrep 'phrase'
[no results]

but it'd be nice if tcsh had a setting to do this automatically?

Afaik there is no such setting. You could try something like

set output = `command`
if ( "$output" == "" ) then
  echo "previous command returned empty stdout"
  echo "$output"

in your scripts (if you're scripting). Not perfect since newlines are removed by command substitution, but maybe a starting point ...
