Nope. It will split ${A} into N words, drop the last word if ${A}
isn't terminated with a delimiter, and put all those words into B.
Actually, on further testing, it looks like what's happening is that
-n throws away the last item in non-newline terminated values.
Yes. More precisely, non-delimiter-terminated.
Not sure if that's intentional, but it's definitely not what the
documents say is supposed to happen.
Working as intended *and* documented:
http://skarnet.org/software/execline/el_transform.html#split
Section "How it works":
The last sequence of characters in the value will be recognized as a
word even if it is not terminated by a delimiter, unless you have
requested chomping and there was no delimiter at the end of the value
before the chomp operation - in which case that last sequence will not
appear at all.
Yeah, splitting + chomping is a bit of a tricky one, but the behaviour
allows you to handle all the cases you may need. :)
