Subject: [PATCH v4 0/6] config: allow user to know scope of config options

From: "Matthew Rogers via GitGitGadget" <[email-masked]>
Date: Fri, 24 Jan 2020 00:21:00 +0000

This was originally a pull request to the git-for-windows repository
[https://github.com/git-for-windows/git/pull/2399]. It adds a new option
--show-scope which would allow a user to see what scope a given
configuration value has (sytem, local, global, etc.).

changes since v3:

 * Cleaned up t1300
 * Expanded test coverage for t1300 to not rely as much on !MINGW by using a
   simpler filename for most tests
 * config_scope_name is now exposed in config.h
 * cleaned up commit messages for clarity/content (again)

Matthew Rogers (6):
  config: fix typo in variable name
  t1300: fix over-indented HERE-DOCs
  t1300: create custom config file without special characters
  config: split repo scope to local and worktree
  config: clarify meaning of command line scoping
  config: add '--show-scope' to print the scope of a config value
