POSIX requires a -h option to sh and set, to locate and remember utilities invoked by functions as they are defined. Given that this locate-and-remember process is optional elsewhere, it seems safe enough to make this option do nothing. POSIX does not specify a long name for this option. Follow ksh in calling it "trackall".
