`split` on `Whitespace` and `splitWhitespace` are not equivalent:
from strutils import split, splitWhitespace
let s = " a couple of \t words "
echo s.split.len # prints 9
echo s.splitWhitespace.len # prints 4
In case of leading whitespace `split(maxsplit = 1)[0]` is empty string while I
expect `splitWhitespace(maxsplit = 1)` be the first non-whitespace token in the
string. Sure, one can strip the leading whitespace before using `split()`, etc.
But as I see, all the functionality for `splitWhitespace(maxsplit =
<something>)` is already there, it is just not exposed via public
`splitWhitespace` interface.
The question is "why?" Is it buggy or what?
