Subject: [PATCH 4/5] merge-tree: improve docs for --stdin

From: "Phillip Wood via GitGitGadget" <[email-masked]>
Date: Sun, 16 Feb 2025 16:37:08 +0000

From: Phillip Wood <[email-masked]>

Add a section for --stdin in the list of options and document that it
implies -z so readers know how to parse the output. Also correct the
merge status documentation for --stdin as if the status is less than
zero "git merge-tree" dies before printing it.
