When automatic hard-wrapping causes some piece of a line to be pushed
to the next line, then a separating space needs to be added at the tail
of this piece only when this piece actually gets prepended.
This fixes https://savannah.gnu.org/bugs/?56185.
Bug existed since version 2.9.2, commit 29f7654a.
When typing a space causes both the succeeding word and the cursor to
be pushed to the next line, then this space (and any contiguous ones)
does need to be snipped (when --trimblanks is in effect).
This fixes https://savannah.gnu.org/bugs/?56180.
Bug existed since version 2.9.3, commit 91073be4.
Do the same as in the previous commit: re-evaluate the start of the
viewport when lines that are located above this viewport may have
changed. This is relevant when softwrap is on.
When only the trailing chunk of a line is displayed on the top row of
the screen, and the unindenting of this line leads to a reduction in
the number of chunks, then the starting point of the viewport needs
to be re-evaluated. For simplicity, do this always when something is
unindented.
This fixes https://savannah.gnu.org/bugs/?56102.

Bug existed since around version 2.9.2.
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.
This fixes https://savannah.gnu.org/bugs/?56119.

Bug existed since version 4.0, commit 4d40bea5.
When the file starts with one or more blank lines, the first paragraph
doesn't start on line 1.
This fixes https://savannah.gnu.org/bugs/?56117.
Bug existed since version 4.0, commit ac8bd2a2.
It is still possible to use --jumpyscrolling on the command line or
'set jumpyscrolling' in a nanorc file, but a user will have to restart
nano when they decide they want chunky instead of smooth scrolling,
a decision that should be rather rare.
This frees up the M-S keystroke to be reused for toggling softwrap.
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.
This addresses https://savannah.gnu.org/bugs/?55997.

Instead of doing a check every time round the loop when it is useful
only the first time, duplicate a bit a code and do the check and its
related action beforehand.
Also, improve some comments.
Also, find_bracket_match() is only called when there is a bracket under
the cursor, so stepping forward will never go beyond the end-of-line,
so the central loop does not need to check for that.
Also, improve a comment and shorten another, change a 'for' to a 'while'
(as the end point is not known), and rename a parameter from a single
letter to a word.
The reading order must be predictable, otherwise things might get
colored differently from system to system.
This fixes https://savannah.gnu.org/bugs/?56012.
Otherwise the user could do something like
^R^X sed -i 's/a/surprise!/g' name-of-current-file <Enter>
and the file being viewed would be modified anyway.
