Yes, this is lazy munging by some proxy server you are running. (IIRC
yhe referer header is optional, but if specified must contain a URI - I
don't think XXXX:XXXXetc qualifies).

rather then using the referer header.

It might be worthwhile generating such links for the output text instead
of depending on the referer header.
