Is there a way to keep sublimity mode for R source buffers, while disabling it for the R console?
ESS puts the R console buffer into
inferior-ess-mode, and the source buffers are in
R-mode-hook runs when you open a new source buffer, so anything you put in that will only effect your source buffers.
inferior-ess-mode-hook runs when you start an R console, so anything in there should only apply to the console buffer and not the source.
