Small example that acts weird

[jsmedn]

Hi

This example doesn't come out as expected:
Unsorted: "B4S B", "B4A B", "B4 B"
Sorted: "B4A B", "B4 B", "B4S B"
Expected: "B4 B", "B4A B", "B4S B"

I'm guessing it compares A in "B4A B" to B in "B4 B".

#12 ?

I guess they could be solved as one ticket, but ignoring whitespace between digits only would fail in this example. It would have to ignore whitespace between word-digit and digit-digit, but not digit-word or word-word. So in the case above it would have to compare:
[B, 4, ' ', B] to [B, 4, A, ' ', B]

It would be best to have the ignoring configurable for all those cases.
