fix(messages): adjust msg_show "empty" kind logic (#37427)

Browse Source 
Problem:  A message ending in an unprintable character may emit a
          msg_show event with the "empty" kind. No empty message event
          for echom "".
Solution: Adjust conditions for emitting "empty" msg_show events.
