Can I make “comment-region” comment empty lines?












3















In LaTeX code I can have:



Lorem ipsum dolor sit amet, consectetur

begin{comment}

adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. 



Ut enim ad minim veniam, quis nostrud exercitation 

end{comment}

ullamco laboris nisi ut aliquip ex ea commodo consequat.


If I use comment-region (in a script) to comment the comment environment in la LaTeX code i obtain:



Lorem ipsum dolor sit amet, consectetur

%% begin{comment}

%% adipiscing elit, sed do eiusmod tempor incididunt ut labore et dolore magna aliqua. 



%% Ut enim ad minim veniam, quis nostrud exercitation 

%% end{comment}

ullamco laboris nisi ut aliquip ex ea commodo consequat.


This is not good because LaTeX interpret the empty line(s) (outside of comment environment) as a paragraph break.



My question is: Can I make comment-region comment empty lines?



I tried customizing (let-bind) the comment-syle variable but all the options I've seen do not comment empty lines.



An alternative could be a "built-in" (otherwise I already know how to make this funcion by myself) function that let me append a string on every line of a region (not a triangle). Remember, I need to do it programmatically.
