/*
'length' is the maximum length of the string; the buffer needs
to be one character larger to accomodate the terminating '\0'.
This is easy to get wrong, so we make sure we write to the
entire length of the buffer to identify incorrect buffer-sizes.
We only initialise the "unused" part of the buffer here, a) for
efficiency, and b) because dst==src is allowed, so initialising
the entire buffer would overwrite the source-string. Also, we
write a character rather than '\0' as this makes spotting these
problems in the results easier.
