[PATCH v5 0/2] repo: add --all to git-repo-info

Hi!

This v5 addresses the issues pointed by Junio in the previous versions. They are two small changes:

- `print_all_fields` now has the same signature `print_fields`

- now it uses `size_t` instead of `unsigned long` in a `for` loop

Lucas Seiki Oshiro (2):
  repo: factor out field printing to dedicated function
  repo: add --all to git-repo-info

         `print_field`, allowing it to be called by functions other than
         `print_fields`.
     
    +    Also change its use of quote_c_style() helper to output directly to
    +    the standard output stream, instead of taking a result in a strbuf
    +    and then printing it outselves.
