Okay, now I found what I think is a more serious missing piece of info in wine-user.pdf.
In page 20, last paragraph, it says one can start off by modifying the sample config file, which "can be found in the directory 'documentation/samples'...
Problem is, I did a file search for 'documentation', and I get like 10 pages of hits I did a file search for samples, and same thing, or worse. In both cases I went through all those instances visually scanning for 'wine' or 'config' and found nothing at all. I know I ought to have the sources somewhere, because when I installed fc2, I said "install everything", and that included sources; but I have no idea where to look for the wine documentation folder.
I have to give up on it for now. Far past my bedtime by now, anyways.. ;-) Cheers!
