Yes, this is a known problem with the 3.1.3 release. It turns out that
the fix for handling &foo; SGML entities in HTML tag parameters had a
couple problems. First of all, it didn't handle & if translate_amp
was false, even though this was one of the main motivations for the fix.
Secondly, it messed up bare &'s in tag parameters.
Torsten posted a patch for this a few days after 3.1.3 was released.
I'm now posting what I think is an improvement on this. Torsten's
patch had a couple potential problems which I think this patch avoids.
(The most serious of these was that a parameter after a bare "&" could
still get stripped out, if translate_amp was true.) Please give this
patch a try and let me know if there are any problems.
