title: Match (and delete) LF character in Notepad++ regex
body: <p>In Notepadd++ the <code>\r\n</code> regex will find all the <code>CRLF</code> combinations.  But I have some lines which end just with <code>LF</code>s. First of all, what is that that?  Next, how can I match and delete just that?  Neither <code>\r</code> or <code>\n</code> works. </p>
