xargs man page shortcuts cut short

[Dan Jacobson]

Usage: xargs [-0prtx] [-e[eof-str]] [-i[replace-str]] [-l[max-lines]]
       [-n max-args] [-s max-chars] [-P max-procs] [--null] [--eof[=eof-str]]
       [--replace[=replace-str]] [--max-lines[=max-lines]] [--interactive]

-p is a shortcut for --interactive but you don't mention them together,
maybe there are others' shortcuts not mentioned too.
