* Write some data.

* This function implements a simple state machine that detects new lines.
* It indents the output and prefixes it with a '#' character.
*
* It returns the number of input characters that were output in in_size.
* More characters than this will likely have been output however any calling
* code will be unable to correctly assess the actual number of characters
* emitted and would be prone to failure if the actual number were returned.
*
* The BIO_data field is used as our state. If it is NULL, we've just
* seen a new line. If it is not NULL, we're processing characters in a line.
