Subject: doc lint: Perl "strict" and "warnings" in lint-gitlink.perl
X-Git-Tag: v2.32.0-rc0~41^2~4
X-Git-Url: http://git.ipfire.org/cgi-bin/gitweb.cgi?a=commitdiff_plain;h=3951eeb6d981cf9b9109c905d773c978e6de3f0d;p=thirdparty%2Fgit.git

doc lint: Perl "strict" and "warnings" in lint-gitlink.perl

Amend this script added in ab81411ced (ci: validate "linkgit:" in
documentation, 2016-05-04) to pass under "use strict", and add a "use
warnings" for good measure.
