Description of Problem:
output from `/usr/bin/xargs --help` appears to be missing the trailing newline

Version-Release number of selected component (if applicable):
findutils-4.1.7-6 (verified in rawhide version as well, likely has not been
fixed in any recent builds)

How Reproducible:
100%

Steps to Reproduce:
1. run `xargs --help`, observe output

Actual Results:
[root@caprice:~/tet]# xargs --help
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]
       [--max-chars=max-chars] [--verbose] [--exit] [--max-procs=max-procs]
       [--max-args=max-args] [--no-run-if-empty] [--version] [--help]
