Test suite tweaks

[Aaron Crane]

Please find attached a patch that makes the following changes to the
test suite:

  - The output for a failing test generated by tests/spencer1.awk is
    more informative.

  - tests/spencer1.awk doesn't run grep in backticks, so the shell
    doesn't subject the pattern to any form of quote removal.  This
    fixes three spurious test failures in tests/spencer2.sh (#91, #92,
    #93).

  - tests/foad1.sh uses the $GREP environment variable as $GREP (not the
    space-protected version "$GREP"), to match the rest of the test
    suite.

  - Add additional generated files to .cvsignore.
