I'm not overly thrilled with this honestly...

Well, if we're going to use a regex library, PCRE is probably the one
to go with.

Yeah, that would be an issue to work around. Maybe if we're building
mod_dav_svn we use Apache's version of PCRE?

I'd prefer to limit it, if we have to have it at all.

Maybe evaluate them at parse time to see if they're invalid?

Another good question...
