Slrn has a feature that Knode does not.  :-(  

When posts have unfashionably long lines, or the screen is small, or the font is very large quoted text will wrap.  

Current behaviour is to align the wrapped parts of quoted lines with the left edge of the window - underneath the quote character, "<".  

Things are more obvious (and more readable) with slrn's behaviour, the wrapped part of quoted lines are indented by two characters.  (The start of the text for a first level quote.)  The maths is very easy when a fixed width font is used, and not hard for a variable width font.  

Things could be made even better than slrn by indenting to the start of the quoted text irrespective of the reply depth or quote indicator used.  

It should not be hard the find the width of "start-of-line, [valid quote character]{repeat as necessary}, space".
