patch 9.0.1966: configure prints stray 6 when checking libruby Commit: https://github.com/vim/vim/commit/e379e21ddc2dc12abea9dcfd0708e27788bb568c Author: Illia Bobyr <illia.bobyr@gmail.com> Date: Sat Sep 30 22:59:27 2023 +0200 patch 9.0.1966: configure prints stray 6 when checking libruby Problem: configure prints stray 6 when checking libruby Solution: redirect stdout to dev/null configure: Do not print "6" when checking for libruby `expr` will print the matched string length to the standard output. Current `configure` output looks like this: ``` checking Ruby header files... /usr/include/ruby-3.1.0 6 ``` The script really only cares about `expr` exit code. closes: #13234 Signed-off-by: Christian Brabandt <cb@256bit.org> Co-authored-by: Illia Bobyr <illia.bobyr@gmail.com>
