[ncl-talk] how do “month_to_annual" deal with the data with time coordinate which can not be divided by 12?

[Dennis Shea]

This is an inadvertent left-over from an 'ancient' special request.

As I recall, the user wanted an annual precipitation total for a region
that had no precipitation in the last 2 months (Nov-Dec) of the last year
of the  array. Hence, summing only Jan-Oct was 'ok'. I did not document
this.

*I do not want to keep this hidden special case.*

The 6.4.0 function will be changed to require that the number of months
must be a multiple of 12. The documentation documentation will be changed
to reflect this

THX for the notifiction!
