Subject: describe tests: support -C in "check_describe"
MIME-Version: 1.0
Content-Type: text/plain; charset=UTF-8
Content-Transfer-Encoding: 8bit

Change a subshell added in a preceding commit to instead use a new
"-C" option to "check_describe". The idiom for this is copied as-is
from the "test_commit" function in test-lib-functions.sh
