By the way, I have tried both the suggested addons and neither seems to be able
to replace say "\n\n" with "###" or "\n" with " " (a blank space).
--------------------------------------------------------------------------------


Regarding to my simple addon, try 





to replace two subsequent line endings (at least it worked on my installation;
if there are problems with this pattern, please let me know per mail (adress in
the script file) or here in forum).

The whole pattern for a replacement could be e.g.:

/

/g, " "

see the info on the home page on matching of single \r or \n
