Re: [PATCH 1/2] grep/pcre2: limit the instances in which UTF mode is enabled

I have to admit that adding to a complex condition might be obscuring
some other edge case, and indeed the fact the test passed even without
this fix is concerning.

From my reading of what Ævar suggested originally[1], it would seem that
the new is_log condition should be on an branch of its own, and more code
should be needed to make sure the contents we are going to use are indeed
utf8 by the time it hits pcre2_*match() before setting it.

At least, let's not consider pursuing this approach to pile on more
iffy code on top of broken code in the release.  Unless I hear
otherwise, I am leaning to revert the whole three patches of the
original series and call it a day for both 'maint' (for 2.34.1) and
'master'.

Thanks.
