If the edit window consists of a single row, then the do_up() call has
already brought the desired line into view -- which means that trying
to scroll then (when already on the first line of the file) would fail.
This fixes https://savannah.gnu.org/bugs/?53891.
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.
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.
When 'afterends' is set and Ctrl+Right or Shift+Ctrl+Right is pressed,
nano will stop at the ends of words instead of their beginnings.

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.

Also, add a period after the "Read nn lines" message, and
don't let the next shell prompt overwrite this message.

This makes the names of these bindable functions equal to the names of
their corresponding options -- like for all the other toggles that have
a corresponding option.
Set the NO_NEWLINES flag to achieve this. And move the saving and
restoring of the global flags to the main speller routine, so the
flags aren't saved and restored for each internal spell fix.

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.

Bug existed since commit 30fc197b (a month ago) which changed the
type of 'i' from int to size_t, causing the comparison to do the
wrong thing when 'threshold' is negative.

The formatter or linter might have changed in the meantime -- when
the filename was changed to have a different extension, for example.
