Bug #11906: File.dirname separator stripping from the begining of path

Description

MRI strips additional leading slashes with File.dirname :

File.dirname "////foo/bar/baz"   # => /foo/bar
File.dirname "////foo//bar/baz"  # => /foo//bar

... issue arose as an incompatibility on JRuby's tracker: https://github.com/jruby/jruby/issues/2391
is the current behaviour really intended?

MRI normalization uses UNIX style normalization. So, that's intentional. I'm curious why JRuby uses another normalization.
Does it have good use-case?

And on Windows, note that \\foo\bar is a valid UNC style path, but \\\foo\bar is not.
