Parsing URL attributes - url-mailto, url-imap, url-ldap broken?

[Diane Murray <disumu@x3y2z1.net>]

I just noticed that `url-mailto' doesn't parse URLs with query
arguments like it used to.  If I call
(url-retrieve-synchronously "mailto:ml+atest@x3y2z1.net?subject=testing")
the word "testing" should be inserted in the Subject field, but it
isn't.  In Emacs CVS of 2006-09-19 it does that.  I'm assuming after
because of the following changes, now it doesn't:

  2006-10-09  Magnus Henoch  <mange@freemail.hu>

          * url-parse.el (url-generic-parse-url): Handle URLs with empty
          path component and non-empty query component.  Untangle path,
          query and fragment parsing code.  Add references to RFC 3986 in
          comments.
          (url-recreate-url-attributes): Start query string with "?", not ";".

I think `url-imap' and `url-ldap' won't work correctly either, from
what I've seen in the source code.

Since the change was probably made to parse http query strings better,
and there is no such use of url-attributes in url-http.el, I believe
it should be safe to somehow revert to the old way, since many of the
other url scheme files depend on that way of doing things.
