What did it do? What did you *expect* it to do?
This looks like it's related to your ongoing project to make your
simple script as complex as possible. As such, it appears you're
digging into the bowels of the Bourne shell and trying to dig up
every obscure piece of syntax you can find, so that you can use
them all, to be completely sure you can't possibly read the script
a week from now.
I advise you to stop doing this.
In this particular instance, you're assigning a LIST of two values
to a STRING variable, using a comma as a delimiter between them.
Presumably you're going to split this list apart later on.
Wouldn't it be a whole lot simpler to store the list in an ARRAY
variable in the first place, and avoid the need to split it?
