Subject: verbs: reset optind (#10116)
X-Git-Tag: v240~714
X-Git-Url: http://review.tizen.org/git/?a=commitdiff_plain;h=010d436e020ab4af57a8b9fc38918f551acc875b;p=platform%2Fupstream%2Fsystemd.git

verbs: reset optind (#10116)

optind may be used in each verb, e.g., udevadm. So, let's initialize
optind before calling verbs.

Without this, e.g., udevadm -d hwdb --update causes error in parsing arguments.
