Why is |input->selectionStart() == input->selectionEnd()| necessary?

This was the part of old change but it is not required now, hence removing this
check.

         input->setSelectionRange(max, max);
     else
-        input->cacheSelectionInResponseToSetValue(max);
+        input->setSelectionRange(input->selectionStart(), input->selectionEnd());

nit: This blank line change is unnecessary.

[harpreet.sk, 2014/07/08 06:07:59]

Done.

 
     if (!valueChanged)
         return;
