Merge branch 'en/merge-recursive-cleanup'
The merge-recursive machiery is one of the most complex parts of the system that accumulated cruft over time. This large series cleans up the implementation quite a bit. * en/merge-recursive-cleanup: (26 commits) merge-recursive: fix the fix to the diff3 common ancestor label merge-recursive: fix the diff3 common ancestor label for virtual commits merge-recursive: alphabetize include list merge-recursive: add sanity checks for relevant merge_options merge-recursive: rename MERGE_RECURSIVE_* to MERGE_VARIANT_* merge-recursive: split internal fields into a separate struct merge-recursive: avoid losing output and leaking memory holding that output merge-recursive: comment and reorder the merge_options fields merge-recursive: consolidate unnecessary fields in merge_options merge-recursive: move some definitions around to clean up the header merge-recursive: rename merge_options argument to opt in header merge-recursive: rename 'mrtree' to 'result_tree', for clarity merge-recursive: use common name for ancestors/common/base_list merge-recursive: fix some overly long lines cache-tree: share code between functions writing an index as a tree merge-recursive: don't force external callers to do our logging merge-recursive: remove useless parameter in merge_trees() merge-recursive: exit early if index != head Ensure index matches head before invoking merge machinery, round N merge-recursive: remove another implicit dependency on the_repository ...
