vim-patch:partial:8.2.3849: functions implementing reduce and map are too long
Problem: Functions implementing reduce and map are too long.
Solution: Use a function for each type of value. Add a few more test cases
and add to the help. (Yegappan Lakshmanan, closes vim/vim#9370)
https://github.com/vim/vim/commit/389b72196e6aaeafe3f907c73d271f2c6b931140
Partial port as this doesn't include handling for non-materialized List.
