rappdirs 0.3.2: 'version' argument is now vectorized, e.g. in user_cache_dir()

[HenrikBengtsson]

Posting in case others run into this and also to make sure this update was intended.

Previously, I've used:

> packageVersion("rappdirs")
[1] ‘0.3.1’
> 
> rappdirs::user_cache_dir("foo", version = c("a", "b"))
[1] "/home/hb/.cache/foo/a/b"

With the new rappdirs 0.3.2, I now get:

> packageVersion("rappdirs")
[1] ‘0.3.2’
> rappdirs::user_cache_dir("foo", version = c("a", "b"))
[1] "~/.cache/foo/a" "~/.cache/foo/b"

The reason appears to be that rappdirs:::file_path(x) is now vectorized;

> packageVersion("rappdirs")
[1] ‘0.3.2’
> rappdirs:::file_path(c("a", "b"))
[1] "a" "b"

> packageVersion("rappdirs")
[1] ‘0.3.1’
> rappdirs:::file_path(c("a", "b"))
[1] "a/b"

The solution/workaround for is:

> packageVersion("rappdirs")
[1] ‘0.3.2’
> rappdirs::user_cache_dir("foo", version = do.call(file.path, as.list(c("a", "b"))))
[1] "/home/hb/.cache/foo/a/b"

Ooops, I'll fix that ASAP.
