[BioC] Inconistent behavior with all/any and Rle

[Steve Lianoglou]

Hi,

I'm not sure what this should actually return. I think I was surprised
that it returned TRUE:

R> all(Rle(rep(FALSE, 0)))
[1] TRUE

R> all(Rle(rep(FALSE, 0)))
[1] TRUE

But ok. Then:

R> any(Rle(rep(FALSE, 0)))
[1] FALSE

R> any(Rle(rep(TRUE, 0)))
[1] FALSE

`any` should be more "permissive" than `all`, shouldn't it? But also,
maybe a 0 length logical Rle should return something else in these
scenarios?
