That's the wrong syntax, but Emacs shouldn't hang...

So it works fine when you use the right syntax for the URL, but the
problem is the misleading message?   (Also noted in bug#42431 and
bug#58302 -- it's not Windows-specific, but a bug in all handling of
`file-name-handler-alist' for non-file "files".)
