[PATCH v2 00/25] list-files redesign

The UI part is the same (or nearly the same) with the last round. The internal data structure is reorignized to avoid abusing string_list. Tests and documentation are added back.

Nguyễn Thái Ngọc Duy (25):
  ls_colors.c: add $LS_COLORS parsing code
  ls_colors.c: parse color.ls.* from config file
  ls_colors.c: add a function to color a file name
  ls_colors.c: highlight submodules like directories
  list-files: command skeleton
  list-files: show paths relative to cwd
  list-files: add tag to each entry, filter duplicate tags
  list-files: add --[no-]column, -C and -1
  list-files: add --max-depth, -R and default to --max-depth=0
  list-files: show directories as well as files

  list-files: add -F/--classify

  list-files: add --cached and --others
  list-files: add --ignored
  list-files: add --unmerged
  list-files: add file modification options -[admADM]
  list-files: delete redundant cached entries
  list-files: make alias 'ls' default to 'list-files'
  list-files: preload index
  list-files: reduce match_pathspec calls in matched()
  list-files: only do diff that is actually useful
  pathspec: move getenv() code out of prefix_pathspec()
