...which I pushed now to master and libreoffice-4-0, with the slight 
modification of keeping the parameter names in XPricingFunctions.idl 
lowercase.  (I would have preferred not to fiddle with .src files post 
feature-freeze, but it looks like that FUNCDATA macro ties those various 
names together, and this hopefully does not affect anything already 
translated anyway.)

Thanks again,
Stephan
