    opts: improve option suggestion

    In case where we have 2 equally good candidates like
    -ftrivial-auto-var-init=
    -Wtrivial-auto-var-init

    for -ftrivial-auto-var-init, we should take the candidate that
    has a difference in trailing sign symbol.

    gcc/ChangeLog:

            * spellcheck.cc (test_find_closest_string): Add new test.
            * spellcheck.h (class best_match): Prefer a difference in
            trailing sign symbol.
