A keycode is either already in byte range (so there is nothing to do)
or it is not and it shouldn't be (so there is nothing to do either).

After initialization, the type of a key is never used nor needed
(other than for meta keys).

Accept the "Esc [ 1 n ~" and "Esc [ 2 n ~" sequences only when they
end with the "~" character, not with any character.

It is nicer to have a predictable cursor position and not see it hop
left and right on differently indented lines.

Those lines don't exist in that mode -- the relevant subwindows are
smaller, or have been made smaller just before.

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.

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.
