vim-patch:8.1.2143: cannot see each command even when 'verbose' is set

Problem:    Cannot see each command even when 'verbose' is set.
Solution:   List each command when 'verbose' is at least 16.
https://github.com/vim/vim/commit/4facea310c2788c88f021b262658b847381a50a8

Cherry-pick Test_tselect() from patch 8.1.2141.
It requires screendump so it won't run.
I cannot port it to a lua screen test.
