Subject: [PATCH] fix: allow capital letters on host match (#1117)

While matching [user@]host[:port], we previously did not allow capital
letters in host.

While this makes sense for a hostname, it does not make sense to make
that restriction for a host. Since this can match on both, we must widen
it to accept characters allowed in host.
