*
* Now, we don't special-case if the line we read with fgets()
* isn't terminated. We don't care about this, since STRING > 78,
* so corrupted input will just be corrupted a bit more. That
* implies that STRING+1 bytes are always sufficient to store the
* result of qp_decode_line.
*
* Finally, at soft line breaks, some part of a multibyte character
* may have been left over by convert_to_state(). This shouldn't
* be more than 6 characters, so STRING + 7 should be sufficient
* memory to store the decoded data.
*
* Just to make sure that I didn't make some off-by-one error
* above, we just use STRING*2 for the target buffer's size.
