[ESS] comma in Julia REPL (change-directory, etc)

[Tamas Papp]

Naturally, I would like to contribute to the ESS, especially since I
find Julia very nice as a programming language but don't want any other
environment than Emacs, so I will be using ESS.

However, Vitalie advised that I wait with pull requests until
https://github.com/emacs-ess/ESS/issues/119 is merged. Until that
happens (which I hope is very soon), I am collecting bits and pieces in
https://github.com/tpapp/ESS-julia-extensions , which I plan to convert
into a PR once 119 is merged.

Best,

Tamas
