[ESS] Ever consider changing indentation on #?

Using 'formatR' to reformat code is relatively easy. I wrote a function,
with the help of Walmes Zeviani, to do exactly that:


It can be bound to the indent function (C-M-\) with:

  (add-hook 'ess-mode-hook
            (lambda ()
              (load-library "ess-indent-region-r")
              (set (make-local-variable 'indent-region-function)

Now, if you want to use that style while coding, that would require a new
indentation style in ESS, which is essentially similar to the R engine
formating style. However, ESS indentation does not currently allow for all
of the perks of R style, notably with respect to call continuation and
indentation after the 5th level.

See this issue in ESS:


Let's say that following the R engine indentation style has been coldly
