[PATCH v3 5/8] update-ref: support symrefs in the delete command

From
Karthik Nayak <karthik.188@gmail.com>
Date
Apr 23, 2024, 21:28 UTC
Message-ID
<20240423212818.574123-6-knayak@gitlab.com>
In-Reply-To
<20240423212818.574123-1-knayak@gitlab.com>
From: Karthik Nayak <karthik.188@gmail.com>

The 'delete' command in 'git-update-ref' allows users to delete `<ref>` after verifying it exists with `<old-oid>`, if given. Extend this command to alternatively take in `ref:<old-target>` which is used to verify if the symbolic ref targets the provided `<old-target>` before deletion. This will only work when used with the 'no-deref' mode as it doesn't make sense to deref a symref during deletion.
