*foo {cheese} bar*

Will not display any bold in the RTE, and will not round-trip correctly. (Quick testing suggests that the round-tripping may not have worked for a while, as does CONF-15460, but it used to at least display correctly in the rte, and maintain some of the emphasis after round-trip.

I think it should be an easyish fix and think any side-effects of the fix will be less bad than the bug.

This bug is a superset of CONF-15853
