I'm leaving this as recipes for now... but we can also do
javascript client-side validation in addition to server-side
validation.

Actually, the form already handles this -- ':)' inside of a
(:var:...:) gets changed into '&#3a;)'.  Similarly, if someone sends
a newline to a  var:... text variable, it's converted to a space.

(We might want to change it so that newline becomes \ or \\.  Hey,
it's configurable.  :-)

This can work, as well as creating automatic forms from pages...
but I'm not sure they'll be terribly useful without a lot of
formatting smarts in them.  Anyway, it's available for people
to write in recipes.
