I'm glad you're both only discussing this hypothetically, then, and both
don't want to allow *** at all.  If `unambiguous' was all it took,
***this*** would be unambiguous, too - this is emphasised *and* strong.

ditto.  And I see no sense in which the space makes it easier to read.

and I'd argue that in '*this*', each ' is adjacent to a word-boundary,
namely the end of the emphasised word this, and likewise that in
***this*** the outer *...* or **...** abuts the ends of the word
obtained by colouring the word using the inner one.
