Avoid formatting "morph help foo" output

The cliapp formatting doesn't understand Markdown. Adding
Markdown support in Morph is more work than there is time
for right now, but we'll do it later. This quick hack just
means we output the raw Markdown rather than something that
is incomprehensible due to ruined formatting.
