Development record

The headless approver refuses a case statement whose pattern is a glob as program-name-unread: case "$1" in a) echo a;; *) echo other;; esac is refused, with or without the leading ( before each pattern, while the same statement with a plain pattern (b) in place of *) is approved. The guard reads the glob pattern after ;; as a command name it cannot fix, so an ordinary default branch cannot run headless.
