# This is a stdin-to-stdout filter that takes TAP output (such as 'make test')
# on stdin and deletes lines pertaining to expected results.
#
# More specifically, if any of the test points in a test file either failed but
# was expected to pass, or passed but was expected to fail, then emit that test
# file's output; else, elide that test file's output.
