- less than twice the size of the format string. This is a very
- arbitrary restriction, but it is an internal restriction, so I'll
- put it in. This means that the %s format specifier is almost
- useless; unless the caller can GUARANTEE that the string is short
- enough, fputs_filtered should be used instead.
