* maint: (41 commits) Clarify commit error message for unmerged files Use strchrnul() instead of strchr() plus manual workaround Use remove_path from dir.c instead of own implementation Add remove_path: a function to remove as much as possible of a path git-submodule: Fix "Unable to checkout" for the initial 'update' Clarify how the user can satisfy stash's 'dirty state' check. Remove empty directories in recursive merge Documentation: clarify the details of overriding LESS via core.pager Update release notes for 1.6.0.3 checkout: Do not show local changes when in quiet mode for-each-ref: Fix --format=%(subject) for log message without newlines git-stash.sh: don't default to refs/stash if invalid ref supplied maint: check return of split_cmdline to avoid bad config strings builtin-prune.c: prune temporary packs in <object_dir>/pack directory Do not perform cross-directory renames when creating packs Use dashless git commands in setgitperms.perl git-remote: do not use user input in a printf format string make "git remote" report multiple URLs Start draft release notes for 1.6.0.3 git-repack uses --no-repack-object, not --no-repack-delta. ...
