[ESS] ess-remote double echo

[Ross Boylan]

I recently updated ESS from git (13.09-2 [git: 
a33a2f9e06185a225af7d72ea3896cfd260e455e]) and notice that ess-remote, 
in R mode, is echoing commands that I send with C-c C-n twice.  I don't 
think that used to be case, though I'm not sure.  I think this used to 
happen if I was in shell model and never executed ess-remote, with the 2 
lines of options it sets.  But this is happening even after I do ess-remote.

Is there a way to get rid of the clutter?

I'm using ESS straight from source; I notice the 13.09-1 release notes say something about binaries
Changes / Selected Bug Fixes in 13.09-1:
    * ess-remote and TRAMP: R support code is now downloaded in binary
      form instead of being injected from local machine.
so maybe I need to do more than just use the source?
