We run through everything in normal.t.pl two times, once
in "standard" mode and once in "paranoia" mode. Print some
context. Also, bail out if file creation fails.
Output now looks like this:
$ ./test.sh
tests/normal.t.pl ...
runTests: mode=standard
tests/normal.t.pl ... 54/116
runTests: mode=paranoia
tests/normal.t.pl ... ok
tests/reverse.t.pl .. ok
All tests successful.
