 > Perhaps extend the `<3` regex to search for any < that don't look like
 html tag start?

 Hm, that seems like it would be very inefficient, but that gives me an
 idea - it looks like we could change the tag regex, currently

 {{{
 "/<(\/?[\w:]*)\s*([^>]*)>/"
 }}}

 to require that a tag be present, like

 {{{
 "/<(\/?[\w:]+)\s*([^>]*)>/"
 }}}

 (and encode any < left sitting in the before-the-tag text).  That seems to
 work fine (and is much simpler), demonstrated in the -2 patch and unit
 test.
