Benno Schulenberg d54180ad8b tweaks: reduce a bit of mark-adjusting code to its essence
It doesn't matter whether the grafted text contains a newline or not.

It only matters whether the mark was before or after the cursor.  When
it was after the cursor, the mark needs to be set to the bottom line of
the grafted text and its x coordinate needs adjustment; and when it was
before the cursor, the mark just needs to be set to the top line of the
grafted text.

Benno Schulenberg 00410d83fc tweaks: rename a function, to be distinct and fitting
It was hard to remember that the "pt" stood for "plus tabs", and the
"len" seemed to say it was about number of bytes instead of columns.

Benno Schulenberg 34d22d3f00 wrapping: improve the persistence of the prepending behavior
Now you can have a look elsewhere in the buffer (and even delete
or paste stuff there) and when you return to the original line
and continue typing, any spillover from automatic hard-wrapping
will spill over onto the same line it spilled over to before.

You can even switch to a different buffer and return and continue
typing, and stuff will still spill over to the same line.

In the bargain, this gets rid of a bit of flag-resetting code
that was run for many keystrokes, in most cases needlessly.

Benno Schulenberg 167a8e5c09 options: make --nowrap override again a contrary nanorc setting
All other options are off by default and can only be switched *on*
(either by a command-line option or a nanorc setting) -- there are
no command-line options to switch them off again.  Except for the
--breaklonglines/--nowrap pair.  So these need special handling.

Benno Schulenberg 2552307064 options: remove -f (--finalnewline); go back to auto-adding this newline
For relatively inexperienced users (as most users of nano probably are)
it is far better that nano produces POSIX text files by default, where
each line ends with a newline character.  This means that these files
will "print" properly (not gluing the next prompt at the end of the
last line), tools will see and process each line of them, and, while
editing, adding text at the end is easier.

Benno Schulenberg 19a833c94e startup: check again for a Linux console after reading all files
When there is a dash among the files on the command line, nano will read
data from standard input, which means that the latter is not connected to
a terminal and thus cannot be recognized as a Linux VT until nano has
finished reading the input and has reconnected the input source to the
terminal.

The first probe for a Linux VT is kept in place for now, so that nano
can stop when there are errors in an rcfile while running on a VT.
(This stopping will not work when data is read from standard input,
of course, but that is a smaller fish.)

Benno Schulenberg 1f39f60b2f tweaks: there is no reason to block SIGWINCHes while waiting for speller
In the past, SIGWINCHes were responded to immediately (which was madness),
but since commit 75d64e67 all a SIGWINCH does is set a flag so that, when
the time comes to update the screen, nano knows the dimensions may have
changed.  The mentioned commit removed most blockings and unblockings of
SIGWINCH, but not this one.

Benno Schulenberg eaeafe29ca suspension: don't try to show the cursor position when going to sleep
As the statusbar() function will write the position directly to the
terminal when not in curses mode, the final part of this position
message will seem to be after the prompt when exiting from nano.

The cursor position will get written correctly to the status bar
anyway, because returning from suspension enters a fake key into
the keyboard buffer, and this key elicits an update of the display.

This fixes https://savannah.gnu.org/bugs/?54639.

Benno Schulenberg 09ab2e3d0e bindings: when Ctrl+Shift+Delete has no keycode, don't use KEY_BSP
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.

Benno Schulenberg e6429e782a bindings: hard-bind <Ctrl+Shift+Delete> to 'cutwordleft'
On FreeBSD and NetBSD (when reached through ssh from a Linux machine)
this has the absurd effect of making <Ctrl+Backspace> do a 'cutwordleft'
by default, out of the box, without needing any rebindings.  Weird, but
wonderful, because the ideal behavior.

Also ensure that <Shift+Delete> always does a Backspace.

This makes that we have the following set of "congruent" keys:

  <Tab> moves text to the right,
  <Shift+Tab> moves text to the left,
  <Delete> "eats" a character to the right,
  <Shift+Delete> "eats" a character to the left,
  <Ctrl+Delete> "eats" a word to the right,
  <Shift+Ctrl+Delete> "eats" a word to the left.

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.

Benno Schulenberg 063a8b0870 startup: show the correct number of lines when opening multiple files
When switching to a different buffer, don't just show its name but

Then use this same message when at startup multiple files are opened
and (after reading them all) we switch back to the first buffer.

(This loses, when multiple files are opened, the information about
format conversion that nano still shows when a single file is opened,
but... this bug has shown that people don't really look at this line
anyway, so... let it be.  The info can still be seen when writing out
the file with ^O.)

Devin Hussey e889c28a95 signals: upon a crash, save changed buffers and reset terminal state
Upon a segmentation fault or an abort signal, instead of crashing,
losing all changes, and leaving the terminal in curses mode, nano
now calls die(), to save any changed buffers and to restore the
terminal to a usable state.

For the remote chance that nano segfaults in die(), the handler for
SIGSEGV and for SIGABRT is reset to its default value as soon as the
signal fires, to prevent a crash-handler loop.

Since a core dump is usually more helpful for debugging, the crash
handler is not included in a debug build.
