* lt/refs: (58 commits) git-pack-refs --prune pack-refs: do not pack symbolic refs. Tell between packed, unpacked and symbolic refs. Add callback data to for_each_ref() family. symbolit-ref: fix resolve_ref conversion. Fix broken sha1 locking fsck-objects: adjust to resolve_ref() clean-up. gitignore: git-pack-refs is a generated file. wt-status: use simplified resolve_ref to find current branch Fix t1400-update-ref test minimally Enable the packed refs file format Make ref resolution saner Add support for negative refs Start handling references internally as a sorted in-memory list gitweb fix validating pg (page) parameter git-repack(1): document --window and --depth git-apply(1): document --unidiff-zero gitweb: fix warnings in PATH_INFO code and add export_ok/strict_export upload-archive: monitor child communication even more carefully. gitweb: export options ...
