  1. You used the wrong list. Please see the posting guide.
  2. They used /minus because they wanted minus not hyphen. R uses Latin1 and not standard encoding, and /minus is in Latin1. I think the fonts you are using are not Latin1 fonts, as all the afms supplied with R support /minus.

If you look at the output with your patch, it uses hyphen for negative numbers, extremely poor typography (the sort of thing that you get from Word!).

3) // is invalid in C code, and your patch will not compile on some systems which R supports.

There is perhaps a way around fonts which are missing /minus, but we want /minus if available. Perhaps you would like to work on a more careful analysis and patch? One that does not break standard usage?
