Re: fixed bug: grep '.' didn't match some Hangul Syllables etc.

[Paul Eggert]

Perhaps the problem is that require_en_utf8_locale_ isn't checking for 
proper support for Hangul Syllables in the en_US.UTF-8 locale, and that 
your Fedora 35 installation happens to lack that support? It'd be odd, 
though, as I tried both plain Fedora 35, and up-to-the-minute patched 
Fedora 35, and they both worked for me. Plus, Hangul Syllables have been 
in Unicode since Unicode 2.0 (1996) and in glibc since 2000 and I don't 
know why they'd be omitted from en_US.UTF-8 in this day and age.

PS. I looked into the problem with the Perl-related tests failing on 
Fedora when Perl is absent, and installed the attached to fix the 
problems I found. This is a different issue of course. (Maybe some day 
we should switch to Python. Oops! Time to duck and run....)
