Yes, the "patch" should be part of kdelibs... you are correct.

QApplication::isRightToLeft()... but... why?

What if I live in Israel, and my desktop is English, or spanish? You will be 
surprized, but a lof of people here use an English UI. We should have a 
configuration in KControl(?), which will be default to off unless:

1) we are in an RTL locale
2) we are in in LTR locale, but XKB has a hebrew/arabic/farsi layout
3) enhanced support for RTL languages is set up in QtConfig

Watch for (2), in Windows Qt3/4 sets on "Enhanced support for RTL..."  if (2) 
is true.

Yes, in my blog I tested the insertion of new paragraphs. In this new code I 
modify existing paragraphs. 

The post you linked to was done when I tried to set up the direction for 
lokalize. Sadly, Lokalize does not set the direction properly under KDE 4.2 
(tested on stock Kubuntu packages). I did not investigate this any further.
