fix(extui): adjust which messages are sent to "more" window

Problem:  Decision whether message is sent to "more" window is based on
          the number of newlines present in a message, rather than the
          actual text height.
          With the "box" target, messages that come from a cmdline
          entered command are not always routed to the more window.
Solution: Still write the message to the target buffer, and calculate
          the actual text height. Postpone updating several state
          variables until after the decision to re-route is made.
          With the "box" target, only consider the text height of the
          message if it is not a message from a cmdline entered command.
