I've committed a change[1] that allows you to set a `symlink` flag for
files and folders to filter out. The function called by
`lfs.dir_foreach()` wasn't designed to do the job of a filter.

   lfs.dir_foreach('/path', function(file)
   end, {folders = {symlink = true}})

should do what you're looking for -- filtering out symlinked directories.
