[BUGFIX] CGL:ArrayBracketSpacingSpaceBeforeBracket

on metrics.typo3.org the violations drilldown
says that are 2 violations against
"ArrayBracketSpacingSpaceBeforeBracket" in
tests/Unit/t3lib/utility/
class.t3lib_utility_mailTest.php.

this should be fixed.

after that i guess this coding guidline sniff
could be activated in the CI-server jobs?
