Re: Patch to document base64 encoding

Patch applies cleanly, doc compiles, navigation tested and ok.

"... section 6.8" -> "... Section 6.8" (capital S).

"The string and the binary encode and decode functions..." sentence looks
strange to me, especially with the English article that I do not really
master, so maybe it is ok. I'd have written something more
straightforward, eg: "Functions encode and decode support the following
encodings:", and also I'd use a direct "Function <...>decode</...> ..."
rather than "The <function>decode</function> function ..." (twice).

Maybe I'd use the exact same grammatical structure for all 3 cases,
starting with "The <>whatever</> encoding converts bla bla bla" instead of
varying the sentences.

Otherwise, all explanations look both precise and useful to me.
