The goal of the patch is to make things easier for users.  The
"hostname:path" syntax is much more common than ssh://... and people
still trip over the double slash thingie (and I'm not even sure that the
RFC(?) that recommended it is still valid).

And I have some vague memories that an "ssh://" URL was supposed to mean
"open a shell in that machine" without specifying what should happen
when there's a path.

So it's not like ssh:// is a standard.

I always find it "funny" when a program tells me "Hi! You said 'foo',
but I'm pretty sure you meant 'bar'. If you really wanted 'bar', say
'bar', OK?" and then fails with some kind of "invalid use of 'foo'"
error.  I.e. it's confident enough that I meant 'bar' to go through the
trouble of showing me that message, but not enough to actually use
'bar'.  That's fine when there could be catastrophic consequences, but I
don't think that's the case here.
