xargs man page "arguments", "filenames"

[Dan Jacobson]

xargs man page:
       xargs reads arguments from the standard input ... and
       executes the command (default is /bin/echo) one or more times
       with any initial-arguments followed by arguments read from
       standard input.
Better better clarify the two kinds of arguments.
Maybe call the standard input ones "items" perhaps, instead of "arguments".

       --null, -0
              Input  filenames  are terminated by...
Whaddayyamean filenames? Shouldn't this be "arguments" or "items"?  Or does it
have magic eyes to single out filenames?
