[Rd] Date class shows Inf as NA; this confuses the use of is.na()

In the following example, the date class shows Inf as NA
> as_date(Inf, origin = '1970-01-01')
[1] NA
This is misleading as is.na() reports incorrectly
> is.na(as_date(Inf, origin = '1970-01-01'))
[1] FALSE
The correct approach here would probably to have an Inf (and -Inf)
*displayed* rather than NA.
