Description: What check_unsafe_options only matched exact canonical names, so an abbreviated option like --upl slipped past the guard and reached git as --upload-pack — arbitrary command execution even with allow_unsafe_options=False. Fix Reject an option when its canonical name is a prefix of any blocked option's name. Empty candidates (e.g. a bare --) are skipped so they don't false-match. Test Added a clone-path regression test covering --upl, --upload-pac, and --conf. Existing unsafe-option tests still pass. Refers: GHSA-f2m5-q89v-8m67.
