I was just following the lead of the template message code. That
excludes an empty template message. I can see that that might be
different though, you can save on the separator adding removing if it is
empty. I'll make the change as you add.

Again I was just following what was there. I was trying to be cautious
to avoid problems on things like win32. I'll factor out the code to do
the editor thing and make it a separate test.
