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
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?
