[ESS] ess-comment-indent

[Joel J. Adamson]

Senor Kasper,

Thanks for the tip.  What happens in R mode is that (you are correct)
I was using single #-marks for comments.

Stata has three comment styles: one is like C 

/* everything in here is a comment; is use this most often */

another is for continuing lines

logit ilike Rbetter, /// comment over here; command continues
  use Emacs for a happy life  

Another which I rarely use since there's no way to automatically
invoke it is to put an asterisk at the beginning of the line

* this is a comment

The meddlesome indentation happens with both of the first two styles.

I will look at the documentation, however, can someone explain why
this happens?  It does not continue the indentation level after a
comment for me as Kasper explained: it either sets the comment over
the to the left side (comment-column), which is nice, or it indents
the next line.  In other words, If I'm writing an indented set of
text, then I put in a comment _on its own line_, the next line will be
indented two columns, not to the distance that the previous text was
indented.
