Fix "commandline --paging-mode" false negative when there is no room for pager, attempt 2

Browse Source 
The previous fix was reverted because it broke another scenario.  Add tests
for both scenarios.

The first test exposes another problem: autosuggestions are sometimes not
recomputed after selecting the first completion with Tab Tab. Fix that too.
