From 17c13e60fd799336b28d320dcba06fe1ef06e01d Mon Sep 17 00:00:00 2001 From: Sergey Organov Date: Tue, 13 Apr 2021 14:41:17 +0300 Subject: [PATCH] diff-merges: introduce log.diffMerges config variable New log.diffMerges configuration variable sets the format that --diff-merges=on 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=on and -m. t9902: fix completion tests for log.d* to match log.diffMerges. Added documentation for log.diffMerges.
