Dave Thomas 1a70916bca set -u doesn't permit bash arrays to test -n
Although set -u allows empty WHITELIST=() list to be set, you can't test
-n "$WHITELIST".  Looks like the intention of the commit that caused
this issue (Change-ID Iad2d490c86dceab148ea9ab08f457c49a5d5352e) is to
set a policy to prevent future use of bugs due to unbound variables.

Thanks StevenK for pairing with me and helping me hone my bash skills.
