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.

When the user configures nano with --enable-altrcname=name,

When the keyboard buffer is empty, return a value that is not equivalent
to <Ctrl+Space>, so that typing a bunch of these while searching is going
on will not result in some of them getting executed afterward.
Indenting/unindenting always happens in a single contiguous block.
Lines that cannot or should not be indented or unindented do not
need to remembered separately as it follows from their content.
That is, do not fall back to the default background color when the
name for the background color is invalid, but reject the entire
color command, just like for an invalid foreground color.
