Nguyễn Thái Ngọc Duy (6):
  match_pathname: avoid calling strncmp if baselen is 0
  dir.c: inline convenient *_icase helpers
  match_basename: use strncmp instead of strcmp
  match_{base,path}name: replace strncmp_icase with strnequal_icase
  dir.c: pass pathname length to last_exclude_matching
  exclude: filter patterns by directory level
