The info is stored in the session database, not the user database.
There should be no reason to need it when a user is not logged in.
Also, hide the email field in the preferences page for openid users.
Note that the email and username are not yet actually used for anything.
The email will be useful for gravatar, while the username might be used
for a more pretty display of the openid.
* moderatedcomments: Added moderate_pagespec that can be used
to control which users or comment locations are moderated.
This can be used, just for example, to moderate http://myopenid.com/*
if you're getting a lot of spammers from one particular openid
provider (who should perhaps answer your emails about them),
while not moderating other users.
* moderatedcomments: The moderate_users setting is deprecated. Instead,
set moderate_pagespec to "!admin()" or "user(*)" instead.
This prevented comments containing some utf-8, including euro sign, from
being submitted. Since md5_hex is a C implementation, the string has to be
converted from perl's internal encoding to utf-8 when it is called. Some
utf-8 happened to work before, apparently by accident.
Note that this will change the checksums returned.
unique_comment_location is only used when posting comments, so the checksum
does not need to be stable there.
I only changed page_to_id for completeness; it is passed a comment page
name, and they can currently never contain utf-8.
In teximg, the bug could perhaps be triggered if the tex source contained
utf-8. If that happens, the checksum will change, and some extra work might
be performed on upgrade to rebuild the image.
