Actually that was my third option in mind _until_ I found the
way to tackle that issue.

But where to make the cut? Just because a regexp uses "(?!…)"? Surely
not! Or because it is too long? Doesn't sound like a valid reason
either.

I'd rather make it even longer using the /x flag and then being able
to add comments.

But that will again break with the one-line-per-entry design of that
file.

Anyway: I think we should _generally_ improve the situation and not
duplicating functionality for a single tag.
