Function postMergeCommand

commands/command_post_merge.go:15–47

postMergeCommand is run through Git's post-merge hook. This hook checks that files which are lockable and not locked are made read-only, optimising that as best it can based on the available information.

(cmd *cobra.Command, args []string)

// This hook checks that files which are lockable and not locked are made read-only,
// optimising that as best it can based on the available information.

	// The only argument this hook receives is a flag indicating whether the
	// merge was a squash merge; we don't know what files changed.
	// Whether it's squash or not is irrelevant, either way it could have
	// reset the read-only flag on files that got merged.

	// so we have to check the entire repo
