Subject: [PATCH v4 1/3] config: rename `git_etc_config()`
Date: Tue, 13 Apr 2021 09:11:44 +0200	[thread overview]
Message-ID: <34bdbc27d618d7467d2caf6844d8c06bdcb8545b.1618297711.git.ps@pks.im> (raw)
In-Reply-To: <cover.1618297711.git.ps@pks.im>

[-- Attachment #1: Type: text/plain, Size: 3932 bytes --]

The `git_etc_gitconfig()` function retrieves the system-level path of
the configuration file. We're about to introduce a way to override it
via an environment variable, at which point the name of this function
would start to become misleading.

Rename the function to `git_system_config()` as a preparatory step.
While at it, the function is also refactored to pass memory ownership to
the caller. This is done to better match semantics of
`git_global_config()`, which is going to be introduced in the next
commit.
