Section 6.3. says:
The encoded output stream must be represented in lines of no more than 76 characters each.
It should say:
The encoded output stream MUST be represented in lines in according to the following algorithm. Choose a maximal line width w not greater than 76. Insert after each w characters a line break. If the last = (the beginning of the encoded checksum) is not at the beginning of a line, one line break MAY be inserted before the last =.
The old formulation allows lines of different length and even empty
