i didnt't realize TRUE<-1

i thought TRUE was something like INF or so, because normally the following is
false (like Duncan wrote):
> In R like C, FALSE is 0 and TRUE is 1

normally in C you define somewhat like
#define FALSE ((unsigned long) 0)
#define TRUE (~((unsigned long) 0))
(ok, there are more aesthetic ways, you can use "signed",...)

but using binary negation makes much sense in many ways. so in C TRUE evaluates
to max( long) (if you use the unsigned variant), and in fact i thought this
would be the implementation in R as well...
