Indeed.

Setting LC_ALL=C in the test setup greatly reduces the test coverage. As far as
I can see, so far, all the grep tests that work on plain ASCII inputs and
patterns were tested in the locale the user happens to be in. But with your
patch, these tests will only be tested in the C locale.

I would suggest to revert this, and to set LC_ALL=C only for the printf
statements. Patch attached.

By the way, init.sh is periodically copied from gnulib into grep; therefore
changes to the grep test suite belong in init.cfg, not init.sh.
