You could convert =00 to a NUL character and let the function return
the string length explicitly, like the append function does, too. It
might make sense anyway, for the same reasons append returns it.

In that case, the Sieve filter could not use the new function. Would
the code police arrest me for suggesting a flag that determines how to
convert =00?
