C TAP Harness 3.4

Nothing particularly exciting in this release of my C testing framework, but aherbert on Github found a segfault in the runtests driver with test lists that had only blank lines and comments. Since I'm releasing some other software anyway, that seemed to be worth a release.

While preparing the release, I found that the test for spelling errors in the POD documentation had some bad assumptions about how to canonicalize paths, so you may want to grab a new copy of that if you're using it in your projects.

You can get the latest release from the C TAP Harness distribution page.
