This looks like a fine clean-up.
I have a vague recollection that automatic initializers
like this are not always accepted:

    char c[6] = { from, 0, ch, 0, to, 0 };

However, the above is nicer syntax than writing it out,
so I'd be happy to leave it, and adjust only if someone
actually reports a problem.
