While reading 2/2, I got an impression that this is "too" flexible
and possibly operates at a wrong level.  I would have expected that
the wildcarding to be limited to the host part only and hook into
match_urls(), allowing the users of the new feature to still take
advantage of the existing support of "http://me@example.com" that
limits the match to the case that the connection is authenticated
for a user, for example, by newly allowing "http://me@*.example.com"
or something like that.

Because you cannot have a literal '*' in your hostname, I would
imagine that supporting a match pattern "http://me@*.example.com"
would be already backward compatible without requiring a leading
question-mark.

I also personally would prefer these textual matching to be done
with glob not with regexp, by the way, as the above description of
mine shows.

Thanks.
