[PATCH] formatter: instead of leaving curses, use full_refresh() to wipe messages |

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.
[If you use the formatter in a way that is incompatible with this
change -- like using an interactive formatter -- please speak up.]
This fulfills https://savannah.gnu.org/bugs/?62789.
