Bug #9618: Pathname#cleanpath creates mixed path separators
https://bugs.ruby-lang.org/issues/9618#change-45715

* Author: Daniel Rikowski

----------------------------------------
When using `Pathname#cleanpath` with a Windows path the resulting path contains a mixture of slashes and backslashes.

~~~
require 'pathname'
path = Pathname.new('c:\projects\ruby\bug\test.rb')
path.to_s               # => "c:\\projects\\ruby\\bug\\test.rb"
path.cleanpath.to_s     # => "c:\\projects/ruby/bug/test.rb"
~~~ 

I'd expect `cleanpath` to use the same path separator for all path segments. The problem doesn't happen on non-Windows platforms because there backslashes are not detected as path separators.

The problem is that the first path segment is added verbatim and only subsequent segments are joined by `File::join`.

Personally I'd prefer it to use `File::SEPARATOR` **only**, regardless of any original separator(s). That way it would blend with the current 'normalizing' behaviour of `cleanpath`, which then could be also used to normalize any existing separator weirdness and - for example - make a path compatible with `Dir.glob` (which can't use backslashes)
