It would be silly for ^W to do a backward search too after using ^Q
once.

^S will be the first thing people will try for saving a file,
and ^Q is somewhat mnemonic because it is to the left of ^W:
it searches backward.

Make these keystrokes available also in the tiny version.

The basic idea is that the cursor is always off, except when it needs
to be on: when waiting for text input, and in a few other cases: when
something was searched and found in the help viewer, and in the file
browser when option -g is in effect.

When multiple files were open and [x/n] was being shown in the title
bar, don't show nano's name and version number when just one buffer
remains open, but show [1/1] instead.  It is less surprising.

When multiple buffers are open, replace nano's name and version number
with an indication how many buffers are open preceded by the sequence
number of the current buffer.

Also bind 'N' to a backward re-search, while retaining 'n' for a
forward one,  This matches the functionality in the help viewer.

So that these functions have bindings by default, and easy bindings.
Add them to the help viewer too, so that searching backward becomes
possible there.

There is no need to retain the (relative) path that the user
specified, so we can simply reuse that variable.

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

A cast on the same line as a variable declaration is superfluous,
because it effectively defines the type of the variable twice.

I like it better that ^X stays in the same position compared to the
main screen: the lower left corner.

This fixes https://savannah.gnu.org/bugs/?51457.

Since all indentation and unindentation is by a tab, or by a tab's
worth of spaces, use tabsize directly.

This is the first step toward splitting them into two dedicated
functions, instead of letting do_indent() handle both cases.

When compiling with 'clang', it would say: warning: expression which
evaluates to zero treated as a null pointer constant of type 'char *'.

This avoids some warnings when compiled with -pedantic:

    ISO C forbids comparison of ‘void *’ with function pointer
    ISO C forbids empty initializer braces

In the tiny version, Ctrl+Left and Ctrl+Right are available only
in the editor itself and in the file browser.

This fixes https://savannah.gnu.org/bugs/?51173.

Achieve this by making the suppression flag global, so that we can
just reset it instead of making an improper call of do_cursorpos().

This fixes the secondary part of https://savannah.gnu.org/bugs/?51134.

It is no longer necessary to assign up() and down() separately for
the help viewer because by now the movement keys have been sorted
in order of ascending stride also in the main menu.

The two string definitions are relocated just to reduce the number
of #ifdefs.

Apparently the curses on SunOS is less forgiving than the one on GNU.
Or rather: delwin(NULL) should just return an error, it shouldn't crash.

Also, allow rebinding the word and block jumping functions
in the tiny version when nanorc files are reenabled.

(This should have been part of 9ea5eef2, four commits ago.)

Also, allow Ctrl+Left/Right with --enable-tiny --enable-browser.

Also remove a superfluous check for 'do_replace' -- it never gets
bound in the Search/Replace menus.

When configured with --enable-tiny --enable-multibuffer,
/do/ include the new-buffer toggle in the Read-File menu.

Add missing spaces, remove excess spaces, and
replace groups of indentation spaces with tabs.
