Subject: bash-completion: remove one more sort and sub-shell
X-Git-Tag: v227~49^2
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=4ed2f1b1f106b84276eaf8cc4d27cca54653845e;p=thirdparty%2Fsystemd.git

bash-completion: remove one more sort and sub-shell

{} is preferred to (), because the first is just grouping, while the
second invokes a separate shell.
