The suppression of auto-indentation, automatic hard-wrapping, and
tab-to-spaces conversion is now inherent in the way the reading-in
of a bracketed paste is handled by the previous commit: as a single
block of text.
This makes an external paste (with mouse or <Shift+Insert>) behave
the same as an internal paste (^U), and also inherently suppresses
auto-indentation, automatic hard-wrapping, and tab conversion.
This fulfills https://savannah.gnu.org/bugs/?54950.
This is a workaround for the VT not being able to handle zero-width
characters properly, displaying them mistakenly as visible characters.
This avoids https://savannah.gnu.org/bugs/?52954.
The problem has existed since forever, but has become noticeable
since the capability for line numbers was added in version 2.7.1.
(The ideal behavior would be that nano would warn the user beforehand,
before the file that is being edited by someone else gets overwritten,
but that would require many more changes. So... just give a helpful
warning -- that's already better than it was.)
(When the new or changed name is that of an existing file AND this
file is being edited by some other editor (or nano itself), then the
behavior is rather strange: nano asks whether to continue, but the
file has already been overwritten and there is nothing the user can
do to cancel or revert things. A later commit should improve this.)
This fixes https://savannah.gnu.org/bugs/?47975,
and fixes https://savannah.gnu.org/bugs/?53883.
Also, do not break overlong lines and do not convert tabs to spaces,
nor interpret a <Tab> as an indent command (when the mark is on).
In other words: accept an outside paste as literally as possible.
This fulfills https://savannah.gnu.org/bugs/?40060.

Also, tell the terminal to switch on bracketed-paste mode, and toggle
a boolean when the start and stop sequences of such a paste are seen.
This boolean can later be used to suppress auto-indent and such.

The file may not be modified when in View mode, so it makes no sense
to prominently show the M-J keystroke in the Search menu when in that
mode, especially since the keystroke does not really belong there.
This addresses https://savannah.gnu.org/bugs/?57574.
The extract() and copy_from_buffer() functions are mainly used for
cutting a line or a region, so move them to src/cut.c. Also move
the function for which copy_from_buffer() is a wrapper.
When suspending nano on a Linux console (or FreeBSD console), the
helpful message about using the 'fg' command overwrote the start
of the second help line, kind of hiding the message. So, output
a double newline before the message to make it stand out.
Also, drop a pointless cursor movement, as endwin() determines
the placement of the cursor all by itself.
