REVISION SUMMARY
  This fixes the width calculation for the argument hint completion
  items. There, the view apparently reorders the column, or hides
  some, and thus the last sibling by column number is not actually
  the right-most one. In truth, the old algorithm even produced
  negative widget values, which prevented the argument hint widgets
  from ever being shown. This patch fixes that.
  
  Note: You'll probably need KDevelop to see the effect.
