OK, a warning before upgrading to this version, and a request for 

Some of the channel names in the list at the end of the script contain 
non-alphanumeric characters that have special meanings in regular 
expressions. As a consequence, switching to this version may cause the 
script to fail to match the channel in the config file with the one on 
the web page.

If you're familiar with regular expressions, this is easy to get around. 
Anyone here *not* familiar with regular expressions?

My suggestion: I change the code (for version 1.45 :-)) to check whether 
the channel name is of the form "/regexp/" and in that case do the 
matching; otherwise just do a straight string match as before. So, users 
familiar with editing config files and happy making their own regular 
expressions can easily take advantage of the new feature, while past 
behaviour isn't broken.

Comments? If I don't hear something interesting beforehand I'll release 
another update with this change tomorrow night.
