The feature was included in v2.11 (released 2016-11-29) and we got no negative feedback. Quite the opposite, all feedback we got was positive. Turn it on by default. Users who dislike the feature can turn it off by setting diff.indentHeuristic (which also configures plumbing commands, see prior patches). The change to t/t4051-diff-function-context.sh is needed because the heuristic shifts the changed hunk in the patch. To get the same result regardless of the heuristic configuration, we modify the test file differently: We insert a completely new line after line 2, instead of simply duplicating it.
