Mark Sapiro reports:

Existing protections against malicious listowners injecting evil
scripts into listinfo pages have had a few more checks added.

A few more error messages have had their values HTML escaped.
The hash generated when SUBSCRIBE_FORM_SECRET is set could have been
the same as one generated at the same time for a different list and
IP address.
