given.

Benno Schulenberg 10c49edd3b prompt: when asking for Yes/No/All, recognize also UTF-8 letters
Letters in other scripts than English often consist of multiple bytes.
When in a UTF-8 locale, correctly gather these bytes from the input and
put them together as the single letter that they are, before comparing
this letter against the translated "Yy", "Nn" and "Aa" strings.

Benno Schulenberg 2d5c917b1a signals: exclude the crash handler from the tiny version
The tiny version contains much less code, so is less likely
to crash.  And the users most likely use it for very simple
and short editing jobs, making the chance of a crash still
smaller.  So the handler would just be bloat.

Devin Hussey e889c28a95 signals: upon a crash, save changed buffers and reset terminal state
Upon a segmentation fault or an abort signal, instead of crashing,
losing all changes, and leaving the terminal in curses mode, nano
now calls die(), to save any changed buffers and to restore the
terminal to a usable state.

For the remote chance that nano segfaults in die(), the handler for
SIGSEGV and for SIGABRT is reset to its default value as soon as the
signal fires, to prevent a crash-handler loop.

Since a core dump is usually more helpful for debugging, the crash
handler is not included in a debug build.

This addresses https://savannah.gnu.org/patch/?9623.

flags aren't saved and restored for each internal spell fix.

Benno Schulenberg 0d9080a22c scrolling: don't redraw entire edit window when cursor goes offscreen
When the cursor is on the top or bottom line of the edit window, and
an <Up> or <Down> pushes the cursor offscreen, then use edit_scroll()
to bring it back into view, instead of using edit_redraw(), because
the latter would redraw *every row* on the screen, which is a waste
of time.
