Commit 84283672853350a84d2a71b72dc06e180cad1587 introduced the regression, and a previous commit introduced the vercmptest.sh test script to track down these issues. This commit solves the problem by removing the previous attempt at locating the pkgrel portions and replacing it with something that performs the correct logic. While tracking down everything I needed to, I also found a mistake in one of the pactests which is fixed here as well as increased the functionality and verbosity of the vercmptest script to both print out each test it is running as well as automatically run the mirror of each test case.
