ASCII code BS should always do a backspace, also on systems where the
"^H" string gets redirected (for rebinding purposes) to KEY_BACKSPACE.

When not unbinding it from its earlier function (in the same menu),
it would result in showing the keystroke twice in the help text.

Bug was introduced a month ago, by commit f81d174f.
The direct call was a leftover of the old unjustify mechanism.
Also, move two statements to the end of the do_justify() routine,
since that is their place in comparable routines.

When multiple buffers are open, the edit window says "Close" for ^X
instead of "Exit" (when one buffer is open). In the help viewer ^X
says "Close". Apparently the idea is that ^X should say "Exit" only
when pressing ^X leads to exiting from nano. Pressing ^X in the file
browser does not exit from nano, so make it say "Close" instead.
(The help viewer says "Close" since version 2.8.6, commit 934a2192.)
When using --preserve, ^S and ^Q are "eaten" by the terminal and
do not reach nano: they have no effect in nano, so the help lines
and the help texts should not mention these shortcuts.
Also, to keep the help lines in the help viewer neatly arranged,
^L is not bound there when --preserve is used.
Not stepping beyond the last line of the paragraph means that the
length of the paragraph is always the difference in line numbers
(between first and last line of the paragraph) plus one.
When leaving the mark on while justifying and then undoing the
justification, things are likely to get messed up. My applying
David's patches only partially caused this breakage.
This fixes https://savannah.gnu.org/bugs/?55074.
Only the first search for a paragraph needs to check whether we're
currently in the middle of a paragraph. When the 'while' loop for
a full justify is executed, all calls of find_paragraph() start
either on the first line of a paragraph or between two paragraphs.
To find a paragraph, what needs to be done is:
a) When not in a paragraph, move forward until we find one, if any.
b) When in a paragraph but not at its start, move back to its start.
c) Move forward to the end of the paragraph, if any.
When, in the 'while' loop for a full justify, 'filebot_inpar' becomes
TRUE, it means that EOF has been reached and find_paragraph() should
not be called again. To allow 'filebot_inpar' to convey this meaning,
it should not be set to TRUE elsewhere, so another boolean is needed
for setting the correct length of the final line of the cutbuffer.
This fixes https://savannah.gnu.org/bugs/?55086.
