Johan, Stephan what's your take on this?

Since what I propose is consistant with the existing code, not agreeing with 
that means *first* finding the bug that Johan mentioned (which is not directly 
related to my modification), starting a review process of the whole code base 
that uses subr.el/split-string (and maybe other places where that regexp bug 
happens), fixing the code to ensure some kind of backward compatibility, etc. 
and *then* applying my change to subr-x...

While we could first change subr-x (string-trim...) so that they behave 
similarly to split-string and then start the bug hunting...
