In path names and file names, 0x0A means an embedded newline and
should be shown as ^J, but in anything related to the file's data,
0x0A is an encoded NUL and should be displayed as ^@.
So... switch mode at the two main entry points into the "file system"
(reading in a file, and writing out a file), and also when drawing the
titlebar. Switch back to the default mode in the main loop.
This fixes https://savannah.gnu.org/bugs/?49893.
(The variable 'pletion_line' is not conditionalized with this option, as
it would become messy. The compiler will probably be able to elide it.)
When using --enable-tiny, it is not possible to use --enable-wordcomp,
because the word completion function uses the undo system.
Executing the 'complete_a_word' function will search from the start
of the current buffer for entire words that begin with the fragment
that is before the cursor, and will complete this fragment to the
first word that is found. Each consecutive call of 'complete_a_word'
will search for the next matching word and will complete the fragment
to that. By default the function is bound to the ^] keystroke.

It can be activated with --linenumbers on the command line or with
'set linenumbers' in a nanorc file, and it can be toggled with M-#.

Add the keycodes and routines to allow the user to forego setting the
mark explicitly (with M-A / ^6) and instead quickly select a few words
or lines by holding down Shift together with the movement keys.
(Some combinations with Shift are swallowed by some terminal emulators.
To work around some of those, the combinations Shift+Alt+Left/Right work
as Shift+Home/End and Shift+Alt+Up/Down work as Shift+PageUp/PageDown.)
Also, when a key string does not denote a Ctrl nor Meta nor Function key,
there is no point in assigning a keycode, because plain characters cannot
be used as a function shortcut.
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.
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 fulfills https://savannah.gnu.org/bugs/?47283.
Don't make it the responsibility of the executed functions to restore
the list of shortcuts of the edit window. Just detect whether another
menu was displayed, and if so, redisplay the main menu.
This allows for commenting or uncommenting a line or a bunch of lines
with a single keystroke (default binding: M-3). The characters used
for commenting/uncommenting are specified by the active syntax file.

Error messages about lock files should not get overwritten by purely
informational messages, only by alerting ones.
This fixes https://savannah.gnu.org/bugs/?47963.
If during startup there are multiple error messages, currently only the
last one remains and can be read. To improve on that, introduce a short
pause between error messages -- even if it's not enough to read them all,
at least the user will be aware that there are multiple ones.
This also causes a few error messages to beep that currently don't beep,
such as when a file is unwritable.
