New bug, looking for source location for setting Calc formulas

Anyone know off hand where I can find the sourcecode to set the the 
Formula and FormulaLocal property. Then, how can I see how changed that 
code last?

A bug was introduced in 4.1 and I am trying to track the developer 
responsible.

So, what is the bug?

Setting the Formula property on a Calc cell has always expected English 
formulas. Use the FormulaLocal property otherwise. The new behavior is 
that the Formula property acts the same as FormulaLocal

I became aware of this based on a post on the mailing list. Turns out 
there was already an open and not verified bug. I have verified the 
behavior but would like to chat with the responsible developer before 
changing to confirmed and asking the responsible party to consider 
backing out their change (as well as can be done after a release). 
Alternatively, I can at least document the new behavior that the two 
properties are identical so you might as well deprecate one.
