  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'.

  # updated so that `lexer.c' should be rebuild.  Then we are running
  # `make' and `make distdir' and check whether the version of `lexer.c'
  # to be distributed is up to date.
  
  # Please keep this in sync with sister test `yaccvapth.test'.
