[PATCH v4 00/13] nd/pretty-formats

v4 fixes comments from v3, mainly in the auto-coloring patch, and uses qz_to_tab_space for changes in t4205. It also fixes a coding style issue in 06/13, spotted in v2 but I missed it in v3.

Nguyễn Thái Ngọc Duy (13):
  pretty: save commit encoding from logmsg_reencode if the caller needs it
  pretty: get the correct encoding for --pretty:format=%e
  pretty-formats.txt: wrap long lines
  pretty: share code between format_decoration and show_decorations
  utf8.c: move display_mode_esc_sequence_len() for use by other functions
  utf8.c: add utf8_strnwidth() with the ability to skip ansi sequences
  utf8.c: add reencode_string_len() that can handle NULs in string
  pretty: two phase conversion for non utf-8 commits
  pretty: split color parsing into a separate function
  pretty: add %C(auto) for auto-coloring
  pretty: support padding placeholders, %< %> and %><
  pretty: support truncating in %>, %< and %><
  pretty: support %>> that steal trailing spaces
