AFAICT, Diane Murray's analysis is correct.  The 2006-10-09 change was
intended to parse http query strings better, but url-http apparently
doesn't use the result; on the other hand, url-mailto and other parts
of url that depended on the old behavior got broken.

Since Magnus Henoch has not responded, I went ahead and reverted the
patch that caused this problem.  After the release, we can re-apply
the patch, and adapt url-mailto etc to the new behavior of
url-generic-parse-url.
