Subject: [PATCH 2/4] xargs: fix hang with -s option if argument doesn't fit
 and cannot be resolved

Reproduce:
printf '12345 1234567890 12345' | ./xargs -t -s 5 echo
printf '12345 1234567890 12345' | ./xargs -t -x -n 1 -s 15 echo

There might still be further work needed for example this behaves differently
compared to GNU xargs:

printf '1234567890 12345' | xargs -t -x -s 20 echo
