Indeed. I found a couple of ways of achieving what I wanted, using the +=
operator being one of them - but this is only available in bash 4.4+ and I
need to support older versions (back to 4.0).

But the 'wipe before assignment' is inconsistent with how bash handles any
other assignment. For example:
FOO=bar
FOO="$bar baz"
will result in FOO = "bar baz", not simply " baz" as happens with the array
assignment.
I can work around the issue using a different syntax, but I thought it might
be worth reporting the inconsistency :)
Cheers,
Darren.
