/* The original intention was to insert a newline after every 78 bytes.

* partially because of the (small) amount of extra space, and
* partially because for line breaks either would have to hardwire
* ascii 10 (newline) or calculate space in bytes to allocate for
* the platform's newline byte sequence. Also need to be careful
* about where its inserted:
* Ascii 85 decoder ignores white space except for one special case:
* you must ensure you do not split the EOD marker across lines.
