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.

When justifying a paragraph, always first squeeze() is called on
the text (which at that moment consists of a single long line),
which means that (in its wrappable part) this line contains only
single spaces as word separators (and maybe a double space after
a period). So there is no need to call the general is_blank()
function -- checking for a space is enough.
Rationale: nano should not wrap inside the quoting part of a line
because it would change the quoting level, which would misrepresent
things, nor should it wrap inside the indentation part because when
the user tries to indent something beyond the target wrapping width,
she/he does not intend to create a line containing only whitespace,
but effectively wants to push the text beyond the wrapping width.
This copies the behavior of the rewrap_paragraph() routine that is
used during justification, so that automatic hard-wrapping ends up
with the same result as justifying.
Also, always do automatic hard-wrapping when --breaklonglines is in
effect, also when --autoindent is active.
This fixes https://savannah.gnu.org/bugs/?57425.
The bug was old -- it existed since at least version 2.0.6.
This furthermore avoids https://savannah.gnu.org/bugs/?57422.

That bug existed since version 4.4, commit 8fce33af.
That is: allow tabs and spaces to be mixed when comparing indentation.
When the mix of tabs and spaces pushes the text of a line to the same
column as on a consecutive line, then those two lines are considered
to have the same indentation and thus belong to the same paragraph.
This reverts the previous commit (594ef222), and improves upon how
nano has behaved since version 2.9.8.
This fixes https://savannah.gnu.org/bugs/?57404 differently.
That is: two consecutive lines are considered to belong to separate
paragraphs when the smallest indentation of those two lines is not
character-by-character identical with the corresponding piece of
indentation of the other line.
In other words: if one line is indented with spaces, and a consecutive
line is indented by the same distance but with tabs, they are taken to
belong to different paragraphs: a justification will not merge them.
This fixes https://savannah.gnu.org/bugs/?57404.
Bug existed since version 2.9.8, commit 432a7d77.
Also, 'hunspell' is sensitive to the 'LANG' environment variable,
so that spell checking will take place for the language that the
user is using, instead of always for English. (This is a behavior
change, and some people may not like it, expecting the spell check
to occur always for English, but... we'll see.)
This increases the chances that spell checking will work out of the box,
without any extra installing or configuration.
This addresses https://savannah.gnu.org/bugs/?57296.
Also, when something goes wrong in the later stages of the pipeline,
the error code would try to close descriptors that are already closed,
which is not right. So, just let exit() handle any file descriptors
that are still open.
When something goes wrong, nano should beep and the status bar should
use the error color (red by default).
This fixes https://savannah.gnu.org/bugs/?57116.
Run the formatting program outside of curses mode, so that any output
(complaints) that it produces will be on the terminal after exiting
from nano -- at least on a terminal emulator, not on a Linux VT.
This also allows the formatter to be an interactive program.
The disadvantage is that the screen flickers when typing M-F.
This fixes https://savannah.gnu.org/bugs/?57104.
For a nonzero exit status of the formatting program, report on the
status bar that the program "complained", but read in the (probably)
reformatted text anyway -- it can be easily undone with M-U. Only
report failure when the intended program could not be run.
This fixes https://savannah.gnu.org/bugs/?57105.
The word "fixer" sounds too much as if the command would be able
to fix mistakes or correct errors. Especially when seen next to
"linter", it sounds as if one does a syntax check and the other
fixes the found mistakes. (Although the command might in theory
be used for this, it is not its intended purpose.)
After the previous change, all remaining calls of parse_mbchar() have
NULL as their third parameter. So, drop that parameter and remove the
chunk of code that handles it. Also rename the function, as there are
already too many functions that start with "parse".
Now all calls of mallocstrncpy() have NULL as the first parameter
(apart from one call in utils.c, but that can be changed), so the
function can be simplified.
The command can be used to run some kind of formatter or corrector or
arranging tool on the buffer. By default the command is bound to M-F.
The formatter/corrector/arranging program must be non-interactive.
