Since commit 1ff7002b1 (xargs: fix handling of quoted arguments, closes
11441) the -n option hasn't worked properly:
$ echo 1 2 3 | xargs -n 1 echo
1
2
3
$
Because state is now remembered between calls to process_stdin() it's
necessary to update the state before any premature return.

As reported in bug 11441 when presented with a large number of quoted
arguments xargs can return 'argument line too long':
seq 10000 29999 | sed -e 's/^/"/' -e 's/$/"/' | busybox xargs echo
This happens because the variant of process_stdin() which handles quoted
arguments doesn't preserve state between calls. If the allowed number
of characters is exceeded part way through a quoted argument the next
call to process_stdin() incorrectly treats the terminating quote as a
starting quote, thus quoting all of the argument separators.

This change retains "or later" state! No licensing _changes_ here,
only form is adjusted (article, space between "GPL" and "v2" and so on).

The source command does not search $PWD, and bash recently fixed itself to
follow this behavior for /bin/sh.
