If there is <a> tag with blank, the internal link will fail.
Please reproduce the bug by following HTML.
(Internal link "section1" can not jump to internal link.)
I am not sure following patch is the best fix. Please review and
install it to the official tree if appreciated.

I've now fixed this in a different manner. Your patch would have bugged
out if the empty anchor was the first element in the buffer, so I just
made it insert a "*" if we have an empty anchor.
The anchoring mechanism should perhaps be implemented in a different
way -- markers instead of text properties, for instance? That way
zero-length anchors would be no problem. Rewriting it in that way
should probably wait until after the feature freeze, though.

Thanks!

The markers is good idea. Inserting "*" is not bad,
but if it is possible, markers is good.
