[Exim] To those testing TLS support:

Below is a small patch for Exim 3.163. Without it, you can't transfer
x'ff' bytes over TLS on systems where "char" is by default signed (e.g.
Sparcs). I have vowed never again to write a program that uses plain
"char" types. I have been bitten by Sun too many times now.

(Steve, this is really all your fault; the broken line was originally in
your code... :-)
