Review request for kdelibs.


Summary
-------

This patch makes a better job at painting klineEdit 'click' message (e.g. in systemsettings 'search' bar) in a way that is similar to what qlineedit::paintEvent does for normal text. 
This notably fixes the vertical alignment of the "click" message for some styles, including oxygen (see attached screenshot)

Testing
-------

Tested with oxygen, plastique, skulpture, and bespin. It was checked that the "click message" is vertically positioned the same as normal text (from user input) is, with all styles 


Screenshots
