I've thought about the current showstopper--that some OSes have a finite
length to regexps. This of course causes problems if there's too many
items in the indexing limits, etc.

It was proposed that there be an HtRegexList to store multiple regexp.
This seems like it might be a nasty performance drain since you'd have to
check through all of the patterns to exclude something. I don't see any
great "compiling" techniques that can be used in the StringList class.

On the other hand, if we have a self-organizing list, it might be a bit
faster--if a pattern causes a hit, it jumps towards the start of the line.
This doesn't incur much overhead and hopefully the patterns that are hit
the most end up towards the front.

If this sounds OK, I'll see what I can do about implementing it this
weekend.
