   Some packages like FFAP can read both a file name and URL in the same
   minibuffer.  With leading "http://"; highlighting of URL is wrong.

I do not understand.  After "http://";, the "http:/" _should _ be
shadowed, because "/" is what is going to be visited.
file-name-shadow-mode should tell me what is actually going to be
visited, not what would be visited if I enabled certain packages.
(And, actually "http://"; visits "/", even if FFAP is enabled: I tried.)

After "/:http://"; tramp is enabled and nothing is shadowed.

What very specifically is wrong with either of these two examples?
What would you expect to be shadowed or not shadowed and why?
