Subject: [PATCH v6 1/4] stash: add --ours-label, --theirs-label, --base-label for apply
Message-ID: <cd9c64ba60ef72accafc779438db816fd0abbf27.1773740139.git.gitgitgadget@gmail.com>
In-Reply-To: <pull.2234.v6.git.git.1773740139.gitgitgadget@gmail.com>

From: Harald Nordgren <haraldnordgren@gmail.com>

Allow callers of "git stash apply" to pass custom labels for conflict
markers instead of the default "Updated upstream" and "Stashed changes".
Document the new options and add a test.
