  tests: enable 'errexit' shell flag by default.
  
  * tests/defs: Enable `errexit' shell flag (near the end).
  Removed redundant comment about the enabling of shell traces.
  * tests/README (Writing test cases): Update, and use nicer
  formatting in a couple of places.
  * All tests: Adjusted by removing now-redundant calls to
  'set -e'.

  # Check that many conditions do not lead to combinatorial explosion.
  # (This is related to PR/352.)
  #
  # On this test, Automake 1.7.x would compute all 2**22 = 4194304
  # possible combinations of conditionals (it would do this five times,
  # to define a01_DEPENDENCIES, a02_DEPENDENCIES, a03_OBJECTS,
  # a04_OBJECTS, and to rewrite bin_PROGRAM), eating all memory, swap,
  # or cpu time it can found.  Although this test won't print `FAIL' if
  # it fails, it will take long enough so it can't go unnoticed.
