Maniphest Tasks: T13518: PHP 7.4 "preg_match_all()" + "PREG_OFFSET_CAPTURE" behavior has changed

rARCb81818b287db: Accommodate PHP 7.4 changes to certain "preg_match_all()" calls

Summary

Ref T13518. The result format of this call changed in PHP 7.4, which causes us to emit "-1" matches because "-1" survives array_filter().

Filter results in a way that should survive both result formats.

Test Plan

Ran arc unit --everything under PHP 7.4.
