For Grep, it depends on how it was configured when building.  The
default configuration uses gettext to translate messages, and this
message is marked as translated.

For Ripgrep, I don't know.

I'm not sure, and I don't have a port here that supports translations
which I could test.  The only hope is if recent versions of Grep are
built in a way that does honor the environment variables, because the
Unix trick of saying "locale=FOO grep ..." doesn't work on Windows:
the locale is a global user-level setting.

Does someone who uses Windows have Grep built with gettext, and could
try setting the various locale-related environment variables?

Agree.
