block definition: locale coverage, tests for the new defaults, wraps

- block-def strings in every locale (English until translated); the
  catalog test requires each locale to carry them.
- A new block's base point starts at 0, and ATTMAN / BATTMAN report a
  drawing without attributed blocks; the tests expect that now.
- Lines over 100 columns wrapped.
