commit 9408563544dc3e8f17a1de13b33ea17aab630cd2

    Improve file:// URL handling
    
    As a repo URL, we're accepting:
    
    * raw windows paths (with both \ and /), e.g.
    
      c:\cygwin repo
      \\machine\share\cygwin repo
    
    * proper file: protocol URLs, e.g.
    
      file:///c:/cygwin%20repo
      file://machine/share/cygwin%20repo
    
    Most non-standard URLs accepted by the old code should work, too.
    Paths longer than 260 characters are not supported anymore.
