POSIX requires this to prevent entering function definitions in history but this implementation does nothing except retain the option's value. In ksh88, function definitions were usually entered in the history file, even when they came from ~/.profile and the $ENV file, to allow displaying their definitions. This is also the first option that does not have a letter.
