[Vitalie Spinu]

Hi Gustavo, 

This and other issues with ess-julia.el have been fixed in git repo.

In this case it would have been a bad idea because setting
comint-process-echoes was making (some) things work only by accident.

In general, because julia is a moving target, ess-julia.el is also
updated periodically. So your changes will likely conflict with core
changes. It is a better idea to propose them here or pull a merger
request on github if you already made a useful change in your fork.

    Best, 
    Vitalie

Speck? It is an arrow (like in this [1] screenshot) and it should show
both on sending scripts from ESS and entering them in process buffer. It
is misplaced currently by one line. Didn't have time to look into it
recently.
