FYI: Fix a 4-year-old used-uninitialized bug in regcomp.c.

[Jim Meyering]

FYI, I hit this while doing pre-release testing for coreutils:
[yes, it affects the latest glibc, too]

        Fix a bug that inhibited much of the utf8-optimization in regcomp.c.
        * lib/regcomp.c (optimize_utf8): Fix a typo, s/idx/ctx_type/,
        that would inhibit utf8-optimization of a regexp containing line-
        or buffer-anchors, e.g., `^', `$'.
