Oh, great. My impression was that such functionality was off the table.

Yes, I want to unspoof the URL. Adding some markings to notify that
this has been done would also be nice, perhaps by adding a 'warning face
to the text or the like.

RLOs are used legitimately, and I think they display you've selected for
them now (a thin blank line) is good. So I don't want to uglify mail
mode buffers just to handle this quite obscure URL UI problem. I mean,
why shouldn't people be able to do this if they want to in a smooth way?
(Ok, bad example, but these overrides are used legitimately in the bidi
community, if I understand my extensive research correctly.)
And displaying http://myspace.com/#/segami/moc.koobecaf//:sptth with a
couple of visible control characters doesn't really solve the problem,
because most people will still assume that that's a link to Facebook,
not to Myspace. Most people are not even aware that this bidi stuff
exists.
