Why on Earth would you use URL syntax for something like that?  Just add
the "further info" property and link that up with a closure from a text
property or whatever

I'm all for retiring the info: and man: schemes (since they are 100%
useless), but don't really see the need to do so piecemeal -- when Emacs
grows a new URL library that functions better than the current one,
it'll only support http(s) and file, so all this junk will disappear in
one fell swoop.
