    Fix -Wstring-concatenation warning.
    
    Fix the following clang warning:
    gcc/spellcheck.c:477:3: warning: suspicious concatenation of string literals in an array initialization;
    did you mean to separate the elements with a comma? [-Wstring-concatenation]
    
    gcc/ChangeLog:
    
            * spellcheck.c: Add missing comma in initialization.
