[O] Both italic and bold at the "edges": a bug?

[Dmitrii Korobeinikov]

   Here is what I mean. Everything in these will be italic-only:

   - /*italic, not bold*/
   - /italic, *not bold*/
   - /*italic*, not bold/

   Is there a reason for not allowing multiple highlighters to start in the
same place?

   Regards,
   Dmitrii.
