diffcore-rename: treat a rename_limit of 0 as unlimited
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.
