Unlike a regular paragraph, marked text may have different quotes and
more than two types of indentation. Handle this by replacing deviant
quotes with the quote of the first line, and deviant indentation with
the indentation of the second line.
This is modelled after Pico's behavior. However, Pico won't do anything
if you do a full-justify while the mark is on. But this is unnecessarily
limiting, so, when the mark is on, nano will handle a full-justify and a
plain justify the same.
This currently does not handle the lead (quoting + indentation) in
justified selections, does not put mid-line justified selections onto
separate lines, and does not strip whitespace after the lead in justified
selections, the latter two of which Pico does. These behaviors are
forthcoming.
concat_paragraph() concatenates a paragraph into a single line, and
rewrap_paragraph() rewraps that line into multiple lines again.
These two will be needed when the justifying of marked text is added.
Instead of passing 'quote_len' to these functions, calculate it directly
in them.
This will be needed when the justifying of marked text is added. When
unmarked text is justified, it is a single paragraph and by definition
has a uniform quoting part. But marked text may be a jumble of lines
that have different quoting parts.
Option -J (--guidestripe) takes a column number as argument and then
shows a vertical, colored bar over the entire height of the buffer,
to aid the user in regulating the width of the text when the terminal
is wider than this desired width.

When the right half of a two-column character gets overwritten by the
">" continuation character, then represent its left half as "[" also
when spotlighting a replacement candidate. Achieve this by calling
display_string() in the overshooting case with 'isprompt' set to TRUE,
which also makes this function reserve space for the ">" continuation
character so spotlight() doesn't need to do this any more.
This fixes https://savannah.gnu.org/bugs/?55679.

The change in commit edc0d628 was flawed. The old logic covered
every case but one: having reached the end of 'buf' but 'column'
still having overshot the screen width. Now cover this latter
case too.
This fixes https://savannah.gnu.org/bugs/?55638 properly,
allowing the next commit to fix another buglet.

In this way, for single-width characters, one can see what character is
ahead of the cursor before actually moving the cursor to that position,
and, for double-width characters, the cursor never sits on a placeholder
but always shows the character that is actually there.
This addresses https://savannah.gnu.org/bugs/?55716.
In the tiny version the feature toggles are absent, so most of the
Meta-key combinations do nothing, and when --with-slang was used, the
<Ctrl+Left/Right> keystrokes do not work (as they produce truncated
escape sequences under Slang), and the <Ctrl+Space> and <Alt+Space>
keystrokes are awkward to type and make no sense. So... use some
of the free Meta combinations to jump a word to the left or right,
since these functions *are* present in the tiny version.
The reload_positions_if_needed() routine can free the existing
'position_history' and allocate a new one. Using the old one,
from before the reload, could lead to a crash.
This fixes https://savannah.gnu.org/bugs/?55792.

Bug existed since the reloading of the position-history file was
introduced, a year and a half ago, in commit bfc53f30.

That is: keep nibbling off characters until a character is eaten that
takes up at least one column.

Bug existed since version 2.8.0, commit 5283acdc.
On small terminals (80 columns or so), ^S and ^Q would be in
the last position of the help lines. But some terminals might
intercept ^S and stop all output (until ^Q is pressed), which
could be unexpected and frustrating. So, rearrange things for
the tiny version so that ^S appears only on very wide terminals.
Also, having two keystrokes for saving the current buffer
(^O and ^S) in the two help lines is wasteful, more so as
in the tiny version there are no ^G help texts.
So, show the more useful M-Q and M-W instead.

If these two command-line options would override an rcfile setting of
their counterpart new option, the user might come to expect being able
to do this also in the future. But these old options will be obsoleted
at some moment, so... better start ignoring them right now.
