Merge branch 'mm/line-log-cleanup' The `git log -L` implementation has been refactored to use the standard diff output pipeline, enabling pickaxe and diff-filter to work as expected. Additionally, metadata-only diff formats like --raw and --name-only are now supported with -L. * mm/line-log-cleanup: line-log: allow non-patch diff formats with -L line-log: integrate -L output with the standard log-tree pipeline revision: move -L setup before output_format-to-diff derivation
