- *\li The base64 encoded text in 'target' will be divided into

- * the 'wordbreak' string. No parentheses will surround
- * the text.

- * Requires:

- *\li 'wordbreak' points to a null-terminated string of
- * zero or more whitespace characters
- *
- * Ensures:
- *\li target will contain the base64 encoded version of the data
