It will be initialized when a new code is started.

This fulfills https://savannah.gnu.org/bugs/?48154.

And hard-bind the keys Ctrl+Up and Ctrl+Down to these functions.

Unlike the paragraph-jumping code, these new functions disregard
any indentation, treating only blank lines as separators.  They
also do an automatic smart home when that option is set.

This fulfills https://savannah.gnu.org/bugs/?48291.

The bug with a leading wide character has been fixed since ncurses-5.9.

See https://savannah.gnu.org/bugs/?31743 for reference.

This fixes https://savannah.gnu.org/bugs/?48540.

Per https://doc.rust-lang.org/reference.html#fn2

, non-ASCII characters are
currently not allowed in stable Rust, so keep it ASCII-only for now.

Also, compose the coloring attributes during initialization
instead of every time when painting something.

Instead of referring to a window that might have been deleted by a
resize, just turn the keypad back on for the two windows from which
input might have been requested.

Also: don't insert KEY_WINCH as the verbatim keystroke.

This fixes https://savannah.gnu.org/bugs/?48532.

This allows the user to specify which other characters, besides the
default alphanumeric ones, should be considered as part of a word, so
that word operations like Ctrl+Left and Ctrl+Right will pass them by.

Using this option overrides the option --wordbounds.

This fixes https://savannah.gnu.org/bugs/?48455.

When the user changes her mind after having pressed Esc, she cannot
unpress Esc, so do that for her by ignoring the escape code when
the subsequent keycode is outside of the normal printable range.

This restores the behavior from before nano-2.3.5 -- except that
Ctrl+Alt+key continues to report an unbound key.

This fixes https://savannah.gnu.org/bugs/?48459.

This prevents many keycode sequences from being misconstrued when a
command key plus other keystrokes accumulate in the input buffer.

This fixes https://savannah.gnu.org/bugs/?48395.

Color-pair numbers and attributes can be OR'd together -- do so,
to save an attron() call whenever the hilite is on.

To make nano save its modified buffers when it runs out of memory.

Also condense some comments, and group keys with the same result together.

Add them so that <Esc> followed by <Home> will simply do "Home" instead of
reporting an unbound key.  The same for <End>, <PageUp> and <PageDown>.

This restores the behavior from before nano-2.3.5.

It is easy to type beside the comma key and hit instead "m" or ".", so
accept also these as a separator between line and column number.  And
when being generous anyway, also accept space, slash and semicolon.

This fulfills https://savannah.gnu.org/bugs/?48305
