All the handling of characters that are not part of a word is nested within
an if (doindex) { ... }, so when indexing is turned off, it doesn't collect
spaces and punctuation at all, not even for the descriptions. I figured
that the picking up of href tags was deliberate, but I didn't know if the
picking up of descriptions was or not. Don't the descriptions get indexed?

Well, when it calls got_href, and it doesn't have something sensible to
give it, it gives it an empty string. It seems AddDescription ought to
check for this, especially after stripping out leading & trailing space,
but right now it doesn't seem to.

Oh, it does create a new string, but I couldn't figure out why it picks the
2nd element in the list returned by ref->Descriptions() as the value for that
string.
