[PATCH 3/6] Facilitate debugging Git executables in tests with gdb

From: Johannes Schindelin <johannes.schindelin@gmx.de>
Date: Oct 26, 2015, 13:15 UTC
Message-ID: <082d6474a31c405b16087f76de7bc5d01faba529.1445865176.git.johannes.schindelin@gmx.de>
In-Reply-To: <cover.1445865176.git.johannes.schindelin@gmx.de>

When prefixing a Git call in the test suite with 'TEST_GDB_GIT=1 ', it will now be run with GDB, allowing the developer to debug test failures more conveniently.
