Can tcsh report 'command had no output'?

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?
