Probably. But I think the test was supposed to test exactly that. I vaguely
recalled seeing something about "\{" in the docs somewhere. I think it was

        * tests/bre.tests: grep '\{' is no longer an error.
        Fix test for interval too large, and enable it.
        * tests/ere.tests: grep -E {1 is no longer an error
        Likewise for a{1, a{1a, a{1a}, a{1,x}.
