[Standards] Need sanity check on an example in XEP-0393: Message Styling

[Tedd Sterr]

Input = ***

Current = * (index 0)
Lookahead = * (index 1)

Is current a styling directive? No, because lookahead indicates no intervening text.

Current = * (index 1)
Lookahead = * (index 2)

Is current a styling directive? No, because lookahead indicates no intervening text.

Current = * (index 2)
Lookahead = EOS

Is current a styling directive? No, because lookahead indicates end of string.



________________________________
So my reasoning here is that if you lazily match to the middle asterisk
in "***" and call it a styling directive, there won't be any text
between them so it's not a styling directive. Then you'd move on to the
next asterisk and the one you just ruled out as a styling directive is
between them (so that one is text and the second asterisk is a styling
directive).

Does that actually make sense?
