Subject: prlimit: show all limits if called without options
X-Git-Tag: v2.21-rc1~180
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=8f71d37bc5c98ee209dcaa14356546724a95c541;p=thirdparty%2Futil-linux.git

prlimit: show all limits if called without options

Fix option parsing: prlimit ran into usage() if called
without arguments which should only be done for surplus
arguments. Instead, it should display all limits.
