From: Elijah Newren <newren@xxxxxxxxx> In commit 89973554b52c (diffcore-rename: make diff-tree -l0 mean -l<large>, 2017-11-29), -l0 was given a special magical "large" value, but one which was not large enough for some uses (as can be seen from commit 9f7e4bfa3b6d (diff: remove silent clamp of renameLimit, 2017-11-13). Make 0 (or a negative value) be treated as unlimited instead and update the documentation to mention this.
