bin/sisu, processing dir related

* e.g. using live-manual/manual as sample, the following should work as expected
  available: ca de en es fr it ja pl pt_BR ro; select: en & ja:
    sisu --html -v en/live-manual.ssm ja/live-manual.ssm
  or for all available translations:
    sisu --html -v **/live-manual.ssm
  (these previously would have broken after processing the first directory)
  sisu command equivalent for all available translations being (unaffected):
    sisu --html -v --glob live-manual
