I wrote (many of) the regexes in OptionsClass, and in my defense I'll note
that (somewhere) at the time I pointed out that they needed to be checked
out by someone more expert at them than me.

It's currently "[\w\.\-\*]+".  Someone here must know offhand what the valid
characters in an email header are, yes?  Or do we just go with flexibility
and use ".+"?
