[ESS] Ever consider changing indentation on #?

Since we're on the topic, is there a style to make the # comments right-justified against
"fill-column" (which is 97 for me, as that makes printouts look good) and/or the window
width? So as you type the comment, it marches leftward. E.g.:
x <- y + z # This comment ends on column 97

And there are a bunch of styles from which to choose a personal default.

There are `off-the-shelf' styles like `Rstudio' that might satisfy Paul's
Setting `ess-default-style' to `Rstudio' gives these settings:
(ess-indent-offset . 2)
(ess-offset-arguments . open-delim)
(ess-offset-arguments-newline . prev-line)
(ess-offset-block . prev-line)
(ess-offset-continued . straight)
(ess-align-arguments-in-calls "function[ ]*(")
(ess-indent-from-chain-start . t)
Or one can customize the `OWN' style and select it. See the
`ess-style-alist' docstring for more details.
