The patch is compatible with "do not return entries that can easily be
shown to be non-directories".

One option is we can decide the patch is compatible and apply it.

If the existing semantics has to be preserved then we can introduce
another flag and use the new flag instead of GLOB_ONLYDIR in

  if (pattern[0] && pattern[strlen (pattern) - 1] == '/')
    flags |= GLOB_ONLYDIR;

and everywhere else where required.
