comment-region and empty lines

comment-region and empty lines

[Tim Robishaw]

Hi there,

I'm trying to use comment-region to turn a few paragraphs into 
comments.  However, after marking the region and applying 
comment-region, the blank lines are NOT commented.  I'd like to use 
the "plain" comment-style I tried all the others and while some of 
them produce commented blank lines [aligned/box/box-multi do, 
plain/indent/multi-line/extra-line do not], these also produce comment 
characters at the end of each line, which I don't want.  Any help 
would be hugely appreciated!  Best -Tim.

,----[ C-h v comment-empty-lines RET ]
| comment-empty-lines is a variable defined in `newcomment.el'.
| Its value is nil
|
| Documentation:
| If nil, `comment-region' does not comment out empty lines.
| If t, it always comments out empty lines.
| if `eol' it only comments out empty lines if comments are
| terminated by the end of line (i.e. `comment-end' is empty).
|
| You can customize this variable.
