My aging eyes first read it as "make crap" ;-).

Should we ove most of it to some other Makefile that lives in t/tap
and keep it outside the primary Makefile?  This is adding about half
a dozen lines to support a sample unit-test.c file to be tested, and
if we are going to have 200 of them would we add a thousand or more
lines?

As a technology demonstration, such a hello-world test may be fine,
but I would have liked to see a more realistic sample that links
with reasonably isolated part of Git codebase, perhaps testing say
functions from <quote.h>.

THanks.
