All the things that we need are located within the first 68 bytes of
the .swp file. We do write byte 1007 when the file is modified, but
we never reference it. We always wrote just 1024 bytes to the .swp
file, so it makes no sense to read in any more than that.
(Vim writes 4096 bytes to a .swp at first, before adding undo stuff
four seconds later. But the 1024 bytes appear to be enough for Vim
to recognize it as a lock file.)
When asking "continue?", I always thought that answering No would mean
that nano would not continue, that it would stop, that it would abort.
But No only means that it will not open the relevant file but continues
anyway to start up. Asking "open anyway?" is more easily understood in
that way.
Unreadable or corrupt lock files are not a user error nor user intent,
so they should not keep the user from editing the corresponding file.
Also, combine some error conditions to compact the code.
This addresses https://savannah.gnu.org/bugs/?57700.
When in view mode, the file cannot be edited, so there is no need to
warn anyone (through a lock file) that the file might soon change.
This fixes https://savannah.gnu.org/bugs/?57694.
At that point, 'u->cutbuffer' will always be NULL, either from the
original creation of the INSERT undo item, or by having been freed
and set to NULL by do_redo().
The 'prev' and 'next' links get assigned to immediately after the
call of copy_node(). And anyway, it does not make sense to link
a copied node to the predecessor and successor of its original.
Also slightly regroup some lines.
Also, the disabling of the keyboard interrupt (SIGINT) must happen
after that initialization call, otherwise ^C will still do nothing
after returning from suspension (when nano is built against Slang).
This fixes https://savannah.gnu.org/bugs/?57656.
Bug existed since version 2.2.0, commit daaf468c.
When the guiding stripe (when softwrapping) will be shown in
a later chunk, it shouldn't be shown in the current chunk.
This fixes https://savannah.gnu.org/bugs/?57654.
Bug existed since --guidestripe was introduced, in version 4.0.
When having prepared a line for displaying on the screen, nano already
determind whether the line extends beyond the right edge or not. There
is no need to calculate again the full width of the current line later.
Just let display_string() make a note whether the piece of text that
it converted to displayable form still has more text coming after it,
and use this note when it's time to show the ">" continuation sign.
Using a static variable is ugly, but passing it along as a parameter
would be even uglier, because for all other calls of display_string()
the parameter would be just a useless burden.
(The diff is stupid. It should just remove 440 contiguous lines, and
add back 440 contiguous lines further down. Instead it tries to find
similarities between what is moved and what remains, and makes a mess.
You have to use --patience or --minimal to get the better diff.)
The plain keys that are valid in the help viewer are a perfect subset of
those that are valid in the file browser, so just use the same function
to do the interpretation for both. It is not a problem that it returns
function pointers for some keystrokes that have no meaning in the help
viewer, because both NULL and an unhandled function pointer result in
the "Unbound key" message.
Allow the user to paste in the character for Yes, No, or All. If the
paste contains more than one character, ignore all but the first.
This fully fixes https://savannah.gnu.org/bugs/?57623.

The tiny version is oblivious of bracketed pastes, as it serves no
purpose: in the tiny version there is no auto-indent nor undo nor
tabs-to-spaces conversion.
Any modifier keys that are needed to start the execution of a macro
(or of a string bind) should not affect the interpretation of the
keystrokes that are contained within the macro or the string.
This fixes https://savannah.gnu.org/bugs/?57660.
Bug existed since macros were introduced, in version 2.9.0.
A control code cannot be a Meta keystroke, and a plain printable
character as key code necessarily means it is a Meta keystroke.
So, comparing just the key code is enough.
Note that DEL_CODE (0x7F) will never occur as input key code, because
it gets translated to KEY_DC in the input routine (or to KEY_BACKSPACE
when --rebinddelete is in effect).
The Shift detection on a Linux console was meant to affect only the
dedicated cursor-movement keys, not <Shift+Meta+character>.
This fixes https://savannah.gnu.org/bugs/?57598.
