1. Both "%" and "@" are legal separators for e-mail addresses, which are
   getting more and more popular as "usernames" for all sorts of web UI
   logins. I doubt they're safe to forcefully overload, even as
   username[0].
2. I don't think that there's *any* printable character which is prima
   facie illegal in Basic Auth usernames. Not even the "," (and "="?)
   that cgi.cfg sets aside as its separator char(s).
3. Suggestion: Make the marker configurable (so that admins can work
   around odd username[0]s already in use), with setting it to '\0' or
   somesuch effectively disabling the new feature (for the rare cases
   where the user base took pride in having really *every* printable
   character covered ;-).

Kind regards,
