[R] RFE: vectorize URLdecode

[Jack Tanner]

In R 2.9.2,

> URLdecode(c("a%20b", "b%20c"))
[1] "a b"
Warning message:
In charToRaw(URL) : argument should be a character vector of length 1
all but the first element will be ignored

Could URLdecode be modified to actually process all elements of the vector, not
just the first?

Thanks in advance
