And rewrap some lines, three of them to make them equal to another.

At that point, ptr will necessarily point at EOL -- *ptr == '\0'.

Also remove an unneeded nulling.

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.

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.

The option now causes nano to trim trailing whitespace also when
hardwrapping occurs while the user is typing.

Also, remove an unneeded pair of braces.

When not finding a .nanorc file in the user's home directory, nano will
look for a nanorc file in $XDG_CONFIG_HOME and in the ~/.config/nano/
fallback directory.  And when not finding a .nano/ subdir in the user's
home directory, nano will look for (or create) the history files in
$XDG_DATA_HOME or in the ~/.local/share/nano/ fallback directory.

This is a partial implementation of the XDG Base Directory Specification:
https://standards.freedesktop.org/basedir-spec/basedir-spec-latest.html

,
for the purpose of reducing the clutter in a user's home directory, and
to make it easier to back up just the configuration files.

If the user uses a single version of nano, they have no need for
--quiet.  If they do sometimes use an older version and don't want
to see the warnings, they can use 2>/dev/null (they could make an
alias for that and put it before the call of nano).

The user told nano to start, thus nano should *start* -- without
halting and without nagging the user.

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.

Without them, nano still compiles for me, with everything enabled,
even when using --enable-debug, --enable-utf8, and --with-slang.

Include the shortcut for 'Uncut' into most menus, and add an uncut
function for the status bar, so that it becomes possible to paste
the first line of the cutbuffer at any text-input prompt.

This fulfills https://savannah.gnu.org/bugs/?48501

Rename the corresponding rc-file option too, of course.

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.)

Eradicate the need for backslashes, so that the start of the nanorc
manual becomes true, where it says that quotes inside strings don't
need to be escaped.  In the bargain achieve that the empty string
always switches commenting off.
