>
> This log shows that my last patch is correct.  The 2004-04-27 change
> decremented line number by 1 to put point to the same line as designated
> by the index line numbers.  And after the 2008-10-18 change that moves
> point one line down, it's necessary to compensate this and to decrement
> by 2.  Patch installed.
