[PATCH v5 0/3] config: add '--sources' option to print the source of a config value

From: Lars Schneider <larsxschneider@gmail.com>

diff to v4:
* improve wording of "exit code" cleanup commit message (Thanks Peff)
* remove t1300 "--show-origin" test teardown (Thanks Peff)
* fix no parameter function prototype (Thanks Ramsay)
* use doublequotes instead of tabs to test quoted paths (Thanks Junio)

I though a while about Ramsay's suggestion to restore the old error messages for config reads via stdin. Since reading the config via stdin is not that common I don't think the increased complexity is worth the effort. Unless Ramsay or someone else feels strongly about it, I would like to proceed and keep the new error messages

Thanks for the review, Lars

Lars Schneider (3):
  t: do not hide Git's exit code in tests using 'nul_to_q'
  config: add 'type' to config_source struct that identifies config type
  config: add '--show-origin' option to print the origin of a config
    value
