+1. I wouldn't make full error-outcome test coverage a condition of patch
acceptance. However, when an author chooses to submit high-quality tests with
that level of detail, our source tree is the place to archive them. I share
Tom's desire for a Makefile target that completes quickly and checks only
those behaviors most likely to break, but not at the cost of letting deep test
coverage dissipate in a mailing list attachment or in the feature author's
home directory.
