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.

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.
Go back to how line numbers were colored in versions 2.7.1 to 4.3 --
coloring the space (when a background color is used) was unintented.

Bug existed since version 4.4, commit 699cacf7.
For symmetry with the help viewer.
Even though the user could still exit with the bare Q, E, or X keys,
these are not listed in the help text, so they don't really count.
As was noted two months ago: nowhere in the manual does it say that
keywords are case-insensitive, and the manual shows all keywords in
lowercase, and all the examples are in lowercase too. So... simply
expect keywords to be in all lowercase.
It allows entering a TAB character at the cursor position while the
mark is on the same line as the cursor, as some users sometimes do.
This refines the feature that was added in version 2.9.2, and makes
it behave like in the Gedit and Kate editors, for example.
This addresses https://savannah.gnu.org/bugs/?57357.

A negative line number given on the command line counts from the end
of the relevant file (-1 meaning the first line from the bottom),
and a negative column number from the end of the relevant line.
The feature was added in version 2.8.5 but not mentioned in the manual.
This addresses https://savannah.gnu.org/bugs/?57342.

When we switch to another buffer, the window may have been resized
since we were last in this buffer, so make sure that 'firstcolumn'
gets a fitting value.
This fixes https://savannah.gnu.org/bugs/?56991.
Bug existed since version 2.8.0, since the softwrap overhaul.
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.)
