t: translate SIGINT to an exit

peff · gitster · commit da706545f7a1 · 2015-03-12T23:22:57.000-07:00
Right now if a test script receives SIGINT (e.g., because a
test was hanging and the user hit ^C), the shell exits
immediately. This can be annoying if the test script did any
global setup, like starting apache or git-daemon, as it will
not have an opportunity to clean up after itself. A
subsequent run of the test won't be able to start its own
daemon, and will either fail or skip the tests.

Instead, let's trap SIGINT to make sure we do a clean
shutdown, and just chain it to a normal exit (which will
trigger any cleanup).
