This took a little longer than I expected as I had to figure out what
Excel actually does in DATEDIF. Please see
https://bugs.freedesktop.org/show_bug.cgi?id=44456
for changes I did and test case document. For the final algorithm of the
function itself best take a look at the current interpr2.cxx as
I spoiled it in between myself ...

Some detailed nitpicks in commit comments :-)

Thanks for getting this going!
