[Rd] normalizePath output depends on existence of directory

Dear all,

I'm not sure whether this is intended behaviour or a bug. The path returns
from normalizePath is different when the directory doesn't exist. I have
included a reproducible example.

path <- tempfile()
missing.dir <- normalizePath(path, winslash = "/", mustWork = FALSE)
existing.dir <- normalizePath(path, winslash = "/", mustWork = FALSE)

> all.equal(missing.dir, existing.dir)
[1] "1 string mismatch"
> missing.dir
[1] "C:/Users/THIERR~2/AppData/Local/Temp/RtmpagA8Gx/filed5c2cd03543"
> existing.dir
