Subject: [PATCH v5 1/6] fetch-pack: refactor packet writing

From: Calvin Wan <[email-masked]>
Date: Thu, 28 Jul 2022 23:02:05 +0000

A subsequent patch will need to write capabilities for another command,
so refactor write_fetch_command_and_capabilities() to be used by both
fetch and future command.
