[ESS] Ever consider changing indentation on #?

[Steven McKinney]

As an old lisp programmer I use # and ## and ### in all my code.

### ####################################
### for code block and function headers
### (this was actually functional in 
###  SPLUS for auto-generating help)
### ####################################

    ## for inline comments in code, and       # brief margin notes

I find it useful, but all things change over time.
