New log.diffMerges configuration variable sets the format that --diff-merges=default will be using. The default is "separate". t4013: add the following tests for log.diffMerges config: * Test that wrong values are denied. * Test that the value of log.diffMerges properly affects both --diff-merges=default and -m. t9902: fix completion tests for log.d* to match log.diffMerges. Added documentation for log.diffMerges.
