Actually, Exim does not seem to need the NUL at many places, with
printf() functions being an exception, otherwise string_cat() would
append a trailing NUL in all cases. I know strncpy doesn't do that,
but it works on fixed size arrays, unlike the Exim string functions.
While talking about it: Does Exim never free memory? I know the processes
are short lived, so there is no long-term leak, but it still looks odd
to me.
