  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'.

  # Test to make sure that -Wportability complains about recursive
  # variable expansions and variables containing `$', `$(...)', or
  # `${...}' in the name.  We support recursive variable expansions using
  # the latter two constructs for the `silent-rules' option, and they are
  # rather widely supported in practice.  OTOH variable definitions
  # containing a `$' on the left hand side of an assignment are not
  # portable in practice, even though POSIX allows them.  :-/
