[PATCH v6 0/4] config: add '--sources' option to print the source of a config value

[larsxschneider@gmail.com]

From: Lars Schneider <larsxschneider@gmail.com>

diff to v5:
* rename 'type' to 'origin_type' as 'type' is too broad a word in the context
  of configuration file (Thanks to the reviewers Junio and Dscho)
* add dedicated patch to rename git_config_from_buf to git_config_from_mem
  (this change was part of the series since v4 as suggested by Junio but
  hidden in the "config: add 'origin_type'" patch)

Thanks,
Lars

Lars Schneider (4):
  t: do not hide Git's exit code in tests using 'nul_to_q'
  rename git_config_from_buf to git_config_from_mem
  config: add 'origin_type' to config_source struct
  config: add '--show-origin' option to print the origin of a config
    value
