Two separate parser parsing the same string to produce (supposedly)
equivalent parse results is a bit disturbing, and I am not sure if
"is_valid" bit helps that.

Adding "user" and "password" members to the struct, and retire the
existing "parser" (instead it would just use the pre-parsed
components stored in the struct) would.  It would be a much more
involved change, and it is something more than we would want to do
in a regression fix patch.

But this series is a new feature development, so...
