/* If -p is used there must be additional arguments. This is to support
* arbitrary arguments to the command specified but has the side-effect
* of being inconsistent with other programs in that the usage
* 'peek -p1n cat' would work, where usually the 'cat' program would
* have to be specified immediately after -p as in 'peek -1np cat'.
* This is fine, though, because all intended usages work fine. */

* argument parsing, unintended usages work as happy coincidence. */
