The comments are coming from the Windows Registry. I can get the
comments output by the script to change if I adjust the key values in
regedit. There's mention in [1] saying:

"We have changed the name of the “Cape Verde Standard Time” time zone
to “Cabo Verde Standard Time." The display name for this time zone is
now "(GMT-01:00) Cabo Verde Islands.""

I guess that will explain the:

- /* (UTC-01:00) Cape Verde Is. */
+ /* (UTC-01:00) Cabo Verde Is. */

Assume that's what you meant?
