It's used within the completion code (try "set | grep exclude", or "set
| less", then search in the output for "exclude"). So while it is not a
variable defined where we can see it with e.g. declare, does seem to be
defined "behind the scenes", but as a local variable. Once the
completions, er, complete, it is gone. I wonder if the completion code
is failing to exclude its own internal variables from the completion
list.
