Well, we don't have buffers of arbitrary length in the script
language, so this issue doesn't arise there.  (But see bug #4706.)

If the buffer excluded \0, then one could use ordinary %s to format
it; if we needed a programmable substring length, we could add a "*"
width specifier as in libc -- printf("%*s", 40, "foo").  Worthwhile?
