[menu] Allow a post-activity timeout to be definedHEADmastercoverity_scan
Allow the "--retimeout" option to be used to specify a timeout value
that will be (re)applied after each keypress activity. This allows
script authors to ensure that a single (potentially accidental)
keypress will not pause the boot process indefinitely.
