statusbar: suppress --constantshow when the terminal has just one row

Browse Source 
When there is just one row, the text to be edited needs to be shown
there, not some meta information about the cursor position.

This fixes https://savannah.gnu.org/bugs/?60563.

Bug existed since version 2.7.0, since nano allows very flat terminals.
