That is, do not fall back to the default background color when the
name for the background color is invalid, but reject the entire
color command, just like for an invalid foreground color.
In the preceding commit, open_buffer() was changed so that it gets
told whether to load into a new buffer or not, so it is no longer
needed to convey this information through a flag.
This fixes a regression introduced by commit 54103d8e: a crash that
can be triggered by running 'nano --restrict' and pressing <Insert>.
This addresses https://bugzilla.redhat.com/1558532.
When the file has just been read, it is in the state that it has
on disk, so there is nothing to undo.
This fixes https://savannah.gnu.org/bugs/?53387.
When the cursor is on the first or last row of the edit window, and
thus Scroll-Down or Scroll-Up would push it offscreen, first move
the cursor away from the edge row and then scroll.
This fixes https://savannah.gnu.org/bugs/?53376.
As, since commit 0e30177d, the scrollup and scrolldown commands
no longer intend to move the cursor, they should not be seen as
movement functions.
Also, it is not guaranteed that functions are ordered in the same
way in the binary as in the source code, so an ordered comparison
of function pointers will not always work.
This fixes https://savannah.gnu.org/bugs/?53333.
When just scrolling and the cursor does not need to change position
(that is: it is not on the first or last row of the edit window),
then edit_scroll() has handled everything and there is no need to
additionally redraw anything or update 'placewewant'.
Instead of keeping the cursor in the same spot on the screen,
let the cursor move with the text (whenever possible).
This makes these functions behave the same as in Vim and Emacs.
This fixes https://savannah.gnu.org/bugs/?53269.

The leak was mistakenly introduced by commit dc3618a1
-- probably as a leftover of testing things.
Help texts are shown without any line numbers, so the full width
of the screen should be used to display the text.
This fixes https://savannah.gnu.org/bugs/?53308.
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.
For cuts, pastes, and inserts, the lines have already been renumbered;
for indents, comments, and replacements, the line numbers cannot have
changed. (And anyway, variable 'f' is not set for those cases.)
Only when lines get split (ENTER) or fused together (JOIN) do the later
lines need to be renumbered. This mirrors what is done for do_redo().
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.
This assumes that all movement functions are located together,
starting with to_first_line() and ending with do_right().
This fixes https://savannah.gnu.org/bugs/?53195.

The implant() function itself cannot be bound to anything, so it
is not in the linked list of functions -- trying to find it would
lead to a NULL pointer, and thus to a segfault.
This fixes https://savannah.gnu.org/bugs/?53233.
Instead of always calling sctofunc(), it is now only called when
in view mode OR when (after the keystroke's function has been run)
no need for a refresh has been established yet.
Commit bb667beb removed do_gotolinecolumn_void() from the MWHEREIS
menu (replacing it with the empty flip_goto() function), so there
is no longer any need to check for this one special case.
The slash is easier to read than the underscore (which almost
disappears at the bottom of the screen), and easier to type
(no Shift needed on a US keyboard), and it kind of harmonizes
with the ^\ for Replace and the M-/ for End-of-buffer.
When using --smooth or 'set smooth', the screen should scroll the
minimum amount needed to get the cursor back into view. (The only
exceptions are search, undo, and redo -- when there the cursor goes
offscreen, the cursor line is centered.)
This change brings the behavior of pressing <Enter> on the bottom
row into line with, for example, pasting a single line. See also
http://lists.gnu.org/archive/html/nano-devel/2018-02/msg00027.html.
When 'refresh_needed' is already TRUE, there is no need any more
to check whether it should be set.
[Those first two calls are leftovers from before the time that
reset_multis() morphed into check_the_multis().]
When characters are added via Verbatim Input or by pressing <Tab>,
the prepend flag should be retained, just like when characters are
typed directly.
This fixes https://savannah.gnu.org/bugs/?52956.
When copying a string, source and destination may not be equal --
complain loudly when they are, instead of failing to free memory.
Also, instead of freeing the destination string and then allocating
it afresh, just reallocate it -- that should be slightly quicker.
When doing for example: ^W xx ^R ^C ^W, the "xx" would again be shown
after the prompt. This is wrong -- when starting a new search, the
current answer should be empty.

Instead of weaving back and forth between do_search()/do_replace() and
search_init() every time that one of the options is toggled, just keep
looping in the latter function until the user presses <Enter>.
The weaving for the do_gotolinecolumn() function remains, but is
shortened to involve only search_init().
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.
This fulfills https://savannah.gnu.org/bugs/?52931.
When a fragment of help text does not contain any whitespace that
we can wrap at, just advance the pointer, because returning zero
would mean we stay forever at the same place: nano would hang.
That is, call display_string() just on the filename, not on the rest
of the prompt text.
This fixes https://savannah.gnu.org/bugs/?52967.

Instead of assuming that the entire contents of the keybuffer are an
escape sequence (even if this is far longer than any escape sequence
can be), remove from the keybuffer only those integers that actually
constituted a sequence, valid or invalid.
This fixes https://savannah.gnu.org/bugs/?48659.
Trimming trailing spaces is good, but we should not trim the space
(or tab or other blank) that the user just typed and that caused the
hard-wrapping to occur.

The verbosity "hid" the really relevant information:
filename, line number, and the error message.
Valid values and other details can be found in the manual pages.
When the palette is getting initialized, it is too late to send any
error messages about the rcfile options to standard error.

When we're just searching, we do want to report the occurrence at
the cursor (after coming full circle) as a match, so that we can
mention that this is the only occurrence. When replacing, we do
not want to replace this match twice.

There shouldn't be two separate variables (but with the same name) that
count the number of digits seen. Fuse them into a single static var.
