Subject: [PATCH v2 02/12] path: move `validate_headref()` to its only user
Date: Tue, 23 Apr 2024 07:07:32 +0200 [thread overview]
Message-ID: <a347c7e6cae257e35c84ace191a8079f1dddc0d4.1713848619.git.ps@pks.im> (raw)
In-Reply-To: <cover.1713848619.git.ps@pks.im>
[-- Attachment #1: Type: text/plain, Size: 3965 bytes --]
While `validate_headref()` is only called from `is_git_directory()` in
"setup.c", it is currently implemented in "path.c". Move it over such
that it becomes clear that it is only really used during setup in order
to discover repositories.
