My opinion is that slashes should not be magical at all, except as
electric key strokes in UI.  If the facility were implemented that
way, I would automatically get the behavior I prefer (and at least
some others seem to agree).

The question I asked is, will "hg://authority//foo" be converted to
"hg://authority/foo"?  Url-handler-mode is clearly broken in 22.1.1.
It doesn't understand the hg: scheme, so after enabling url handler
mode, C-x C-f C-a C-k "hg://" ==> "/" in the minibuffer, and even
worse, C-x C-f C-a C-k "file:///Users/steve//.zshrc" RET ==> wrong
type argument: stringp, nil.  I hope/assume this works better in 23,
but maybe you should check.
