You're completely right if we don't limit the discussion to colons. I'm
not sure if breaking colons really makes tools aware that they need to
take care of commas, but "it's broken anyway" is a reasonable answer if
we can have a generic fix (and we can have it here).

So what should the generic escaping look like?

And I still think we should do something about colons, they are much
more common in paths than commas. Even more so on Windows, I guess.
Should we still implement the strategy "anything that isn't a valid
protocol must be a local file"?
