There is a problem with the way this syntax is being handled by the
patch. It's because of the way it detects the "@" that separates
user:pass and host:port. It fails because the username and/or password
could have[0] an "@" in them.

This is basically a problem if some user whould like to use (e.g.)
radius realms[2], in order that the username becomes something like
username at realm.

Yeah. Actually the guys from Gentoo are including this patch in the
rsync 2.5.6 package.

(Note: Please CC to me, as I'm not subscribed to the list)

[0] RFC 2617 (HTTP Autentication) defines the userid field as TEXT[1]
excluding ":".
[1] RFC 2616 (HTTP) defines TEXT as any OCTECT (any 8-bit sequence of
data) except CLTs, but including LWS.
[2] RFC 2138 (Radius) defines a field as "name at fqdn"
