When the series is applied on top of Git 2.54, or on top of f65aba1e (codeql: bump actions/cache from 4 to 5, 2026-04-13), the result does not pass its self test, at least for me.

It seems that the exit status of some error path (subcommand parse failure, presumably) has changed unexpectedly? As I am mostly offline for this and next week, I didn't dig any further.

Thanks.
