* nd/struct-pathspec: (22 commits)
  t6004: add pathspec globbing test for log family
  t7810: overlapping pathspecs and depth limit
  grep: drop pathspec_matches() in favor of tree_entry_interesting()
  grep: use writable strbuf from caller for grep_tree()
  grep: use match_pathspec_depth() for cache/worktree grepping
  grep: convert to use struct pathspec
  Convert ce_path_match() to use match_pathspec_depth()
  Convert ce_path_match() to use struct pathspec
  struct rev_info: convert prune_data to struct pathspec
  pathspec: add match_pathspec_depth()
  tree_entry_interesting(): optimize wildcard matching when base is matched
  tree_entry_interesting(): support wildcard matching
  tree_entry_interesting(): fix depth limit with overlapping pathspecs
  tree_entry_interesting(): support depth limit
  tree_entry_interesting(): refactor into separate smaller functions
  diff-tree: convert base+baselen to writable strbuf
  glossary: define pathspec
  Move tree_entry_interesting() to tree-walk.c and export it
  tree_entry_interesting(): remove dependency on struct diff_options
  Convert struct diff_options to use struct pathspec
