Re: xargs prompts with the same string, but executes differently

[積丹尼 Dan Jacobson]

P.S.,
$ xargs --help
  -I R                         same as --replace=R
  -i, --replace[=R]            replace R in INITIAL-ARGS with names read
                                 from standard input; if R is unspecified,
                                 assume {}
...

Don't you want to mention one is deprecated? Or even remove the
deprecated one from --help entirely?
