This also prevents the message from spilling into the help lines
when the terminal is less than four columns wide. (Not that one
can read anything then, but it looks better.)
For horizontal scrolling, it is not the /desired/ column position that
is relevant for determining whether a line needs to be redrawn after a
cursor movement, but the /actual/ column positions before and after.

Leave the rest of any escape sequence to be processed normally, which
should be possible because those characters are all in ASCII range.
This fixes https://savannah.gnu.org/bugs/?48318.
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.
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.
This fixes https://savannah.gnu.org/bugs/?48532.
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.
This prevents many keycode sequences from being misconstrued when a
command key plus other keystrokes accumulate in the input buffer.
This fixes https://savannah.gnu.org/bugs/?48395.
Add them so that <Esc> followed by <Home> will simply do "Home" instead of
reporting an unbound key. The same for <End>, <PageUp> and <PageDown>.
This restores the behavior from before nano-2.3.5.
Just allocate ample space up front and thus discard the delaying 'if' for
each and every character. In most cases this will allocate far too much,
but that hardly matters: it is freed again as soon as the line is printed.
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.
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.
CONST_UPDATE is only relevant when in the main menu, not when in the
browser. So, check for that condition, instead of saving, changing,
and then restoring the setting.
Cancelling a search should restore waiting mode for the keyboard,
just like at the other exit points of the search routine.
And when the input routine has read in multiple keystrokes, it
should not blindly switch back to waiting mode, but only when
that mode was on before.
This fixes the second half of https://savannah.gnu.org/bugs/?47438.
When the terminal is very narrow, there is little point in showing only
part of the version string -- and chewing off one or two digits from the
version number might even give someone a wrong idea. The user is better
served with always showing the full filename, as long as it fits in the
available screen width.
This fixes https://savannah.gnu.org/bugs/?47703.
For some reason the keyboard code seems to assume that all integers
waiting in the keybuffer form a single sequence. But this isn't the
case: when there is an escape (0x1b) among them, then that is where
a new sequence starts. So, prevent the input code from considering
an escape after a non-escape as part of the current sequence.
This fixes https://savannah.gnu.org/bugs/?47839.
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.
Also, don't force a full refresh of the edit window simply because the
current line needs to be horizontally scrolled. And further, when the
adjustment of edittop has determined that a full refresh is needed,
get out and don't bother scrolling some lines first.
The old_current line needs to be redrawn only if it differs from current,
and if it wasn't drawn already by the iteration for when the mark is on.
Also make the conditions involving horizontal scrolling more precise.
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.
On iTerm2 on OS X, the Option+Arrow keys produce special sequences
that start with two escapes. Catch these sequences and interpret
them appropriately as WordLeft / WordRight / Home / End.
