+Subject: [PATCH] fix: validate split short-option values
+
+<!-- agent -->
+
+Single-character keyword arguments are transformed into an option token and
+a separate value token. The unsafe-option candidate builder only checked the
+keyword name, allowing an option-like value to bypass guards shared by clone,
+remote, revision, blame, and archive operations.
+
+Include dash-prefixed values only when short options are actually split,
+including sequence values, while preserving bare values and the non-splitting
+compatibility path.
+
+Git baseline a23bace9 defines clone -n and --upload-pack as distinct options,
+matching the argv boundary this validation now preserves.
+
+Refs GHSA-r9mr-m37c-5fr3.

+CVE: CVE-2026-73625
+Upstream-Status: Backport [https://github.com/gitpython-developers/GitPython/commit/e8d0fbf774d1f6baa3b481adfe48bd262e43b453]
+
+Backport Changes:
+- Omitted test/test_git.py because the current PyPI source archive 
+  does not include the test suite and the python3-git recipe does 
+  not run it.
