[PATCHv3 0/2] 'git config --names-only' to help the completion script

This is a reroll of 'sg/config-name-only'.

  * Instead of the two new listing options of the previous round add one
    new option '--names-only' to modify the output of '--list' and
    '--get-regexp' options, as suggested in previous discussions.
  * Reorganized the commit messages: don't go into details of the
    completion bug in the first patch modifying builtin/config.c, talk
    about that in the second patch.

SZEDER Gábor (2):
  config: add '--names-only' option to list only variable names
  completion: list variable names reliably with 'git config
    --names-only'
