Thank you Paul for taking an action for this one.

I have some questions in your suggested update:

> +Rule   Morocco   2038   only   -   Sep    30    3:00   0   -
> +Rule   Morocco   2038   only   -   Oct    30    2:00   1:00   S
> +Rule   Morocco   2038   max   -   Oct    lastSun 3:00   0   -

With this change, GMT offset at Africa/Casablanca around year 2038 would 
be - 


Rule    Morocco 2037    only    -       Oct      11      3:00   0       -

2038-01-01 - GMT+0

Rule    Morocco 2026    max     -       Mar      lastSun 2:00   1:00    S

2038-03-28 - GMT+0 -> GMT+1

Rule    Morocco 2038    only    -       Sep      30      3:00   0       -

2038-09-30 - GMT+1 -> GMT+0

Rule    Morocco 2038    only    -       Oct      30      2:00   1:00    S

2038-10-30 - GMT+0 -> GMT+1

Rule    Morocco 2038    max     -       Oct      lastSun 3:00   0       -

2038-10-31 - GMT+1 -> GMT+0


For me, above GMT offset transition looks really weird. I suspect what you 
really wanted to suggest would be:

+Rule   Morocco   2038   only   -   Sep    30    3:00   0   -
+Rule   Morocco   2039   max   -   Oct    lastSun 3:00   0   -


Thanks,
Yoshito
