[go-nuts] os.RemoveAll: type of returned error from Lstat

Hi all,

while looking at os.RemoveAll I came across following code snippet:

  // Otherwise, is this a directory we need to recurse into? dir, serr := Lstat(path) if serr != nil {
   if serr, ok := serr.(*PathError); ok && (IsNotExist(serr.Err) || serr.Err == syscall.ENOTDIR) {
    return nil
   }
   return serr
  }


I wonder why the returned error of Lstat is tested this way. According to
the docs (and the source code of Lstat) errors returned by Lstat are always
of type *PathError.

Regards,

Heiko
