Use printf's ability to align things (instead of trying to do it
ourselves and failing when the tab size of the terminal is not 8.)

If functions deeper down would put up some message on the status bar,
it should not be cleared. The chance that messages from a spell-check
program stay onscreen is minute: the edit window is fully refreshed,
the status bar is fully drawn, and the help lines (if there are any)
are redrawn. Only the title bar is not refreshed, but the chance that
an error message has spilled onto the top row... And anyway, the
spell checker should not print any error messages at all.
When parsing an included syntax file, stop reading when a command other
than 'syntax', 'header' or 'magic' is encountered. The syntax file is
fully parsed the first time that a file needs it. Each 'extendsyntax'
command is stored for unloaded syntaxes and applied after the syntax
is loaded.
Closing a buffer does not unload the syntax, even if no longer used by
another buffer.
This addresses https://savannah.gnu.org/bugs/?54928.

This is needed to implement the demand loading of syntax files, as any
errors that these files may contain would otherwise overwrite things on
the screen and the messages wouldn't be on the terminal when nano exits.
It also allows nano to start up on a Linux console when there are errors.

When the data is fed to nano through a pipe, it is pointless to print
this message as it can be seen only after nano has exited.
This addresses https://savannah.gnu.org/bugs/?56348.
The blank filename should not give any match, but maybe the header line
or the magic finds a fitting syntax.

Trying to append does not work on a fifo, and we'd like to be able to
open a fifo again. Also, the append test causes a close event for the
given file at the moment of opening it, which makes using 'inotify' for
waiting for this file to be closed useless.
Commit f8f90272 added the append test, but the original request
(https://lists.gnu.org/archive/html/info-nano/2009-05/msg00000.html
by Damien Joldersma) asked only for a warning when the user did not
have enough privileges to write to the file.
So, drop the append test and just check the access bits.
This fixes https://bugs.debian.org/583196
and fixes https://savannah.gnu.org/bugs/?29312.
The original requests (https://bugs.debian.org/551717 by Paul Wise,
and https://savannah.gnu.org/bugs/?45383 by Mike Frysinger) asked
only that specifying a directory instead of a file name should not
open a new buffer. But commit 98ffb642 excluded everything that was
not a normal file. This avoids a hang when the user accidentally
tries to open a pipe or a socket, but also prevents any user from
doing so on purpose. And opening a fifo can be useful when wanting
to handle sensitive data that shouldn't be stored on disk.
This prepares the fix for https://bugs.debian.org/583196.
When wanting to exit after having modified a buffer by mistake, I don't
want to politely answer a question by typing precisely an unmodified N,
I want to give a command: ^N, meaning *No!*. Or seen another way: I
don't want to be obliged to let go of the Ctrl key before typing N.
When at startup --tempfile was used, the user can discard a modified
buffer with ^O ^Q. It would be nice when (without --tempfile) ^X ^Q
would work too.
Also, compute the required space for the keystrokes more tightly:
most of those characters are plain ASCII, so that means 17 bytes
for 17 cells, and at most one of those characters is a three-byte
arrow, which means 2 bytes extra. Adding the two newlines at the
end, the needed room besides the description is 21 bytes.
Fall back to using the words "Left", "Right", "Up", and "Down",
instead of graphical arrows.
This fixes https://savannah.gnu.org/bugs/?56313.
Bug was left to exist since the Alt+arrow keys were introduced,
in version 2.8.7, commit 1cc030f7.
If the cursor is near the bottom row when softwrap gets switched on, the
screen should scroll just the amount needed to keep the cursor onscreen.
This fixes https://savannah.gnu.org/bugs/?56317.
Bug existed since softwrapping was introduced in version 2.1.11.
The quotes of an empty string ('' or "") should be colored just like
those of a non-empty string, because otherwise the text *between* two
empty strings on the same line gets colored.
Add an extra rule to discolor triple quotes again to not make them
look like valid by themselves.
Also, remove six superfluous backslashes.
This addresses https://savannah.gnu.org/patch/?9801.

The integrated spell checker does not use regular expressions, and
'refresh_needed' is set to TRUE anyway, so the tidy_up_after_search()
call there is effectively a no-op.
The 'keep_cutbuffer' variable becomes FALSE whenever there is cursor
movement or there was a marked region. Use this variable to simplify
the condition for creating a new ZAP undo item. But then typing the
'zap' shortcut should not cause the variable to be set to FALSE.
This fixes the first part of https://savannah.gnu.org/bugs/?56261.
Bug existed since zapping was introduced, in version 3.2.
After the previous change, a copy command will break a chain of cut
commands, so there is no need any more to verify that the line number
hasn't changed.
When 'last_action' has a specific value, then necessarily there must
exist a corresponding current undo item.
(The condition is already absent in do_deletion(), for the BACK and DEL
undo items, and it works fine there.)
