R devel - Jun 1999 - as.numeric with trailing spaces (PR#213)

For R bugs:

"as.numeric" fails on strings with trailing spaces:
(OK in Splus 3.4).
> as.numeric(c("2"," 3","4 "," 5 "))
Warning: NAs introduced by coercion
[1]  2  3 NA NA
>
occurs in both "rw0641b" and "R-base-0.64.1-4-i386.rpm".

Thanks for R

Could probably be argued that one deserves what one gets in that case,
but it'll be easier just to change it.... (*endp == '\0' after
strtod
needs to check for blank-or-empty string instead).
