[issue17618] base85 encoding

Martin Morrison added the comment:

Ok, having now looked at mercurial's implementation... it looks like they implemented the RFC1924 version, whereas my implementation is the Ascii85 version (and I verified it against, amongst others: http://www.tools4noobs.com/online_tools/ascii85_encode/ ).

The Ascii85 version is what is used with PDF, and the default output format for the equivalent Ruby library, so seems useful to have. So I guess what might be desirable is to have both in the codebase?
