Determine the actual number of bytes the striped character consists of,
instead of assuming it's simply one, and determine the real column that
the character starts in, instead of assuming it's the stripe column.

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.
This fulfills https://bugs.debian.org/916392.

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.

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.
To make it obvious that they are not actual characters in the file.
The default highlighting is in reverse video, but this can be changed
to bold by using --bold or 'set boldtext'.
This fulfills https://savannah.gnu.org/bugs/?55571.
The angular brackets look a bit like arrows and thus hint much more
at the idea of continuation than a dollar sign.

When the screen's edge leaves just one column for a two-column
character, then show its left half as "[" and its right half as "]".
(They used to be shown as ">" and "<", but these characters will be
repurposed in the next commit.)
This addresses https://savannah.gnu.org/bugs/?55657.

It needs to be trimmed and substituted with a single-width placeholder
to prevent the continuation character ">" from getting pushed to the
next row.
Also, use the correct width for the answer so that the continuation
character is only displayed when the answer does not fit any more.
This fixes https://savannah.gnu.org/bugs/?55620.

When a line ends with a two-column character, and this character straddles
the edit window's edge, then, although we've reached the end of 'buf', we
have exceeded the 'beyond' column and this two-column character needs to
be trimmed from the 'converted' string, otherwise it would get printed on
the next row.
This fixes https://savannah.gnu.org/bugs/?55638.
Bug existed since version 2.8.0, commit 5283acdc.
After a series of escapes, also <Shift+Meta+letter> should be recognized
as a command keystroke, not just <Meta+letter>.
This fixes https://savannah.gnu.org/bugs/?55442.
Bug existed since the ignoring of <Escape>s before a valid command
keystroke was introduced in version 3.0, commit ecc9211a.
When the terminfo selected by TERM does not match the terminal and
the <Delete> key behaves the same as <Backspace> (deleting leftward)
or the <Backspace> key behaves the same as <Delete> (deleting without
moving the cursor), then using just -d or --rebinddelete should make
the deviant key behave correctly again without affecting the other.
