Oooh! Thanks a lot for all those. I'm going straight with embolden3 now.

Well, it's ugly input as well, so it's not that surprising. For my
purposes, I can declare this to be erroneous :)

Well, I've worked with TWiki including some dabblings in the source, and
definitely don't want to reproduce something quite like that again. Hence,
what I'm actually doing with these tags is to build docbook, which I can
XSLT using these new-fangled libxml bindings. :)

(And it might not be for an actual wiki, either; I have other web-based
document-management ideas in mind that require a markup format for all the
content; I'll see how that evolves, although it's been a year or more
cooking in my head so far...)

Thanks greatly for fixing the regex stuff, though :)
