formatter: instead of leaving curses, use full_refresh() to wipe messages

Browse Source 
This makes invoking the formatter cleaner, by giving feedback and *not*
leaving curses mode.  Leaving curses mode had the small advantage that
any messages from the formatter would be on the terminal after closing
nano.  But it had the disadvantage that invoking the formatter flashed
the screen.

This basically reverts commit 2b9f0619 from three years ago and then
solves the issue of intruding formatter messages in a different way.

This fulfills https://savannah.gnu.org/bugs/?62789.
