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

[Tamas Papp]

Pressing , in the Julia REPL brings up choices for changing the
directory etc, but these appear to be unimplemented for Julia.

I would like to implement them, can someone please suggest another
language used by ESS that I could use as an example? Perhaps not R,
since some functionality (eg vignettes) is not present in Julia so I
would need to add/remove features.

Best,

Tamas
