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.
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.
When we get a ^J as verbatim input, it is not possible to include it
into the file buffer or the prompt answer, because this would mean
adding an encoded null to the buffer or answer, and that is not what
the user intended. One option would have been to simply ignore a ^J
in verbatim input. But the choice has been made to act the same way
as when the ^J (0x0A) is found in the file data: start a new line.
That is the same response as to the Enter key, yes -- but the code
for the Enter key is ^M (0x0D), not ^J. So, to be more precise,
rename the relevant variable from 'got_enter' to 'got_newline'.
Keystrokes are single integers (aided by the flags meta_key and
func_key) but in the input stream they can be encoded as escape
sequences (a series of bytes). Characters are values in byte
range, but in UTF-8 one character can consist of multiple bytes.
Also rename two variables, because the secondary input buffer
that they refer to contains only characters (mostly just one),
never any shortcuts; and there are too many "kbinput" already.
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.
To add a character, one does not need to allocate twice its size.
And the amount to be moved does not depend on the size of the new
character; it just needs to include the terminating zero.
(This fixes in do_output() the same logical mistakes that were fixed
in do_statusbar_output() last February, in acf19bd and 7c0e433.)
Specifying an operating directory should either lead to a successfull
confinement, or nano should fail to start.
(Also: save the terminal settings as soon as possible, so that an early
die() will not restore uninitialized values.)
This fixes the first part of https://savannah.gnu.org/bugs/?47798 properly.
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.

Move the initialization of the operating directory to after the
initialization of the screen, so that the above error can be shown.
This fixes the first part of https://savannah.gnu.org/bugs/?47798.
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.
Since nano-2.4.1, reading in or pasting a large piece of text would put
the cursor on the bottom line, leaving only one line of the non-read or
non-pasted text visible. This is different from the centering behavior
of Pico, and somewhat disorienting, as you can't see "where you are" any
more in relation to the file as it was.
So now center the cursor whenever the read or pasted text is larger than
the screen, but don't center it when the text fits entirely on the screen.
(The latter avoids the effect of the screen jumping unnecessarily when
inserting just a few lines while the cursor is near the bottom.)
To achieve this behavior: default to focusing, and temporarily set it to
FALSE when the focusing effect is unwanted.
This fixes https://savannah.gnu.org/bugs/?47841.
For a little contrast with the function edit_refresh() -- it's
annoying that when you search for the latter you get to see all
the settings of the flag too.
The function edit_update() is called by edit_refresh() itself, so it is
silly that the first sets 'edit_refresh_needed' to TRUE. This setting
is needed only in a few cases -- in the others it's not needed because
the screen does not need to be refreshed (it was just about positioning
the cursor), or 'edit_refresh_needed' has already been set by a call to
goto_line_posx(). So, just set the flag in the five places that need it
and spare the other four calls.
Since commit dac0aa1, nano would leave edittop at current after reading
data from standard input, meaning that everything that had been read in
was invisible, "scrolled off" the top of the screen. Correct this by
explicitly setting edittop.
The above does not happen for ^R (^X) because it has a special mechanism
to save and restore edittop. Nor does it happen for ^R ^X M-F because it
sets current to the top of the file and refreshing the screen will make
edittop follow, or -- in case just one unterminated line was read in --
edittop will already be equal to current.
Instead of saving the current value of placewewant, then setting the
new value, and then passing the old value to edit_redraw() in seven
different places, just let edit_redraw() do this saving and setting.
In the bargain placewewant is now only recalculated when it matters
-- when allow_update is TRUE -- and not when it's superfluous.
Add a third mode of scrolling, FLOWING, besides CENTERING and STATIONARY.
This is used for word and paragraph jumping (and for bracket matching,
but that worked correctly already), and only when focusing is FALSE.
The new mode prevents the screen from scrolling too many lines when
there are several blank lines at the bottom of the edit window and
the next word or paragraph is out of view.
This fixes https://savannah.gnu.org/bugs/?47194.

Add check in reset_multis for CNONE type since that's slowing us down and is dumb
to leave out.

* Add new argument to reset_multis for force redraws without attempting to
guess whether we need to, force updates when running a non-viewok function.
New utility function color.c:reset_multis_for_id(). Fixes e.g. incorrect
highlighting when cutting text.

* nano.c (precalc_multicolorinfo) - Add debugging so we have a better clue if further
issues arise. Also start at the beginning of later lines when trying to match the
end of a multi-line regex. Fixes more overly aggressive highlighting found by
Mike Frysinger. Finally, advance to the match end for performance.

* New option -q, --quiet, rcfile option "quiet" implemented. Skips printing
errors about the rcfile and asking user to press enter. Also, nano should
now only ask for one enter press when there is an error when not using -q.
Based on discussion between Eitan Adler and Mike Frysinger.
* rcfile.c (parse_keybinding) - Significant cleanups and fixes for
detecting and reporting errors in key bindings code.
