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.

This fixes https://savannah.gnu.org/bugs/?48635.

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

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/?48389.

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.
