Babel and Regul written by Gerard Meunier are 
far more sophisticated.  Try them.  RX is for 
simpler tasks.

Two hours spent studying Regul will be a 
better investment.

True as far as I know for RX.  Regul does not 
have that limitation.

That allows you to match the whole line 
to the end rather than a substring of 
the line.

Easily done with ET.  Just mark the text 
with MR.  ET.Search to the mark.  Replace 
with a CR.  Repeat or use RepAll.
