config: format bools gently
Move the logic for formatting bool config values into a helper method and use gentle parsing when needed. This makes 'git config list --type=bool' not fail when coming across a non-boolean value. Such unparseable values are filtered out quietly. Signed-off-by: Derrick Stolee <stolee@gmail.com> Signed-off-by: Junio C Hamano <gitster@pobox.com>
