Yes, currently the regex is looking for a word boundary after the token as a match.
slashes, question marks. etc. are word boundaries.
Testing for pre and post whitespace will work for the link use case.
But it will break if the acronym is written in parenthesis eg. (YMMV) would fail to match.
(I can’t say how often that might be the case, but you just know someone will bring it up)
