+Subject: [PATCH] Check joined short-option values before Git execution
+
+<!-- agent -->
+GHSA-wvpp-8hx9-p66j reports that unsafe-option checks omitted the value
+joined to a one-character option when split_single_char_options was false. A
+regression test reproduced the mismatch: GitPython checked only -n even though
+it emitted a joined -nVALUE token that Git parses as clustered short options.
+
+Collect the exact joined token for unsplit one-character keyword arguments so
+the existing clustered-short-option validation sees every option character.
+The split form and long-option behavior remain unchanged.
+
+A broader audit confirmed that all guarded keyword-forwarding APIs use
+_option_candidates, including clone, ls-remote, fetch, pull, push, archive,
+revision, diff, checkout-index, and tag paths. Git cf5497b14 confirms repeated
+short-option parsing within a joined token. Focused candidate and unsafe-option
+tests pass.
+
+CVE: CVE-2026-76220
+Upstream-Status: Backport [https://github.com/gitpython-developers/GitPython/commit/96a888f4d782cb2f80452148e48e60ce4af6d541]

+Backport Changes:
+- Omitted test/test_git.py because the current PyPI source archive
