Already using pointer/length strings allows to use strings with NUL
characters, and I need to do that in the SIEVE implementation when
decoding MIME strings. This little patch is all I need for that. I don't
think Exim uses strings with NUL characters anywhere, because that's the
focus of MIME. It may become an issue if Exim offers a rfc2047_decode
function, which it currently doesn't.
