When curses gives no code for Ctrl+Shift+Delete, do not fall back
to KEY_BACKSPACE, because then ^H and/or <Backspace> get bound to
'cutwordleft'.
This fixes https://savannah.gnu.org/bugs/?54642.
Bug was introduced with version 3.0, commit e6429e78.
Since the last version, the user can filter an entire buffer through
an external command. This external command can also be a formatting
program, so there is no longer any need for this specific and special
formatter command.
Bind the until-now unbound function 'cutwordright' to <Ctrl+Delete>.
The complementary function, 'cutwordleft', is not bound by default
because on many terminals the keystroke <Ctrl+Backspace> generates
^H -- the canonical ASCII backspace character. We cannot change the
existing action of ^H without upsetting some users.

When executing a command in the current buffer and piping this buffer
(or marked region) to that command, then the cutting of the existing
text and the insertion of the new text should be undone and redone
together, as to the user they appear as a single operation.

When 'afterends' is set and Ctrl+Right or Shift+Ctrl+Right is pressed,
nano will stop at the ends of words instead of their beginnings.

First the two that add something (ADD, ENTER), then the three that
delete something (BACK, DEL, JOIN), and then the one that changes
something (REPLACE). Then the SPLITs, CUT, PASTE, and INSERT, and
then the INDENTs and COMMENTs, when they exist.
The 'f' variable is used only in the ADD, BACK, DEL, ENTER, JOIN, and
REPLACE undo/redo cases. So, avoid making a somewhat costly call when
it is entirely superfluous. Rearrange the undo types to make checking
for the above six types easier.
In this way a single keystroke can produce a fragment of text or a
series of commands, or a mix of the two. It is like a prerecorded
macro.

Each leading tab is converted to two tabs, and any leading four spaces
is converted to one tab. The intended tab size (for keeping most lines
within 80 columns) is now four.
Unset the "Modified" marker only at the point where the file was last
saved -- if there is such a point, because it can be missing when the
undo stack was discarded.

The pointer not being NULL is enough indication that the mark is set.
Also, rename the pointer from 'mark_begin' to simply 'mark', since
the former is kind of pleonastic.
This is modeled after the comment/uncomment code. Each line's
individual indent is saved in the string array of the undo
group structure.
This fixes http://savannah.gnu.org/bugs/?46860.
The function does not contain any comment-specific code, so it can
be used to handle any kind of multiline undo item.
Also, extend the undo group structure to contain an array of strings,
one for each line in the group. When indent/unindent is hooked up to
the undo/redo code, this will allow the latter to restore the exact
original indents.
The new option 'set selectedcolor' applies to marked text, to the
currently selected file in the file browser, and to the highlighted
match during interactive search-and-replace.
For some reason, when returning from suspension, SLang will produce
either a clipped error code (0xFF instead of 0xFFFF, when returning
from an externally induced suspension), or it will clip the code of
first subsequent keystroke to a single byte (when returning from a
normal, in-editor suspension: ^Z).
Side-step this by ignoring the clipped error code, and by using an
undefined control code as the first fake keystroke. Ignoring the
clipped error code is not possible when using a single-byte locale,
otherwise the user would not be able to type the character with
code 0xFF (although it could still be entered with Esc Esc 255).
This fixes https://savannah.gnu.org/bugs/?51477.
Extend get_softwrap_breakpoint() to break softwrapped lines on
whitespace when a flag is set. This flag is controlled by the new
rcfile option "atblanks". The '>' characters marking two-column
characters at the edge of the screen are disabled when it's on.
If get_softwrap_breakpoint() can't find whitespace in screen range, it
will break the line on the screen edge. (In this case, a blank can be
on the last column of the screen, but text can't, so that a blank on the
last column doesn't become invisible and possibly break the display.)
This fulfills https://savannah.gnu.org/bugs/index.php?49959.

When the active syntax contains a comment command that specifies the
empty string, this should override the default comment of "#" and
should disable the Meta-3 keystroke.
To achieve this, the comment string is now set by default to "#" for
all syntaxes, so that it will be set when no comment command is given
(including for the "none" syntax), and is unset only by explicitly
specifying «comment ""» in a syntax file.
