No. That's the bizarre part. Simply doing //server will result in an
error. (See the result of "dir \\Windows" at the command-line).

irb(main):008:0> unc = "\\\\server\\share\\dir1\\dir2\\file.txt"
=> "\\\\server\\share\\dir1\\dir2\\file.txt"
irb(main):009:0> File.dirname(unc)

File.dirname(File.dirname(File.dirname(File.dirname(File.dirname(unc)))))
=> "\\\\"

As noted, \\server is not a valid UNC path. \\server\share is
equivalent to C:\.  In all cases \\\\ is invalid.

Yes. I'll raise it again. I *can* write the changes -- but they're
significant and probably depend on the m17n strings that Ruby 2.0 is
supposed to provide. This is definitely not a Ruby 1.8 item.
