This is v3 of a patch I originally sent in mid-2019: https://lore.kernel.org/git/20190726150818.6373-9-avarab@xxxxxxxxx/ Back then we were near a release and the PCREv2 feature I'm using in 4/4 wasn't in any released version. Now it's in widely used releases, so we can use it and fix some long-standing TODOs in invalid UTF-8 grep matching edge cases.
