--colors broken on OpenBSD

When running the tests for an upcoming OpenBSD port I noticed that the --colors test fails:

This happens both with and without MALLOC_OPTIONS set to S. Note that even when run without --colors the memory reporting is odd:

1421/-390MB [ ]

With #22 applied this is fixed:
