In this case you could also just do: --exclude=$^excludes

As to why your ${=...} result sometimes differs, the most obvious thing that
comes to mind is IFS getting changed somehow. But i don't know how that would
be happening intermittently. As far as debugging, i guess just add logging to
show what IFS is set to immediately before the command, and/or run the script
with -x if you can?
