Since commit 4c6ec637 from about half a year ago, the 'action' parameter
of update_undo() is unused. Verify that this parameter matches the type
of the item at the top of the undo stack, so that in another half year
the parameter can be safely removed.
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.

When the mark is off, initialize not just 'bot_x' but also 'top_x'.

Bug existed since the justifying of a marked region was introduced,
four days ago, with commit f7f5514e.
When there is a dash among the files on the command line, nano will read
data from standard input, which means that the latter is not connected to
a terminal and thus cannot be recognized as a Linux VT until nano has
finished reading the input and has reconnected the input source to the
terminal.
The first probe for a Linux VT is kept in place for now, so that nano
can stop when there are errors in an rcfile while running on a VT.
(This stopping will not work when data is read from standard input,
of course, but that is a smaller fish.)
This fixes https://savannah.gnu.org/bugs/?55912.

Bug existed since the recognition of modified cursor keys on a Linux
console was introduced, in version 2.6.3, commit 290d278f.
This matches Pico's behavior. However, Pico doesn't add the quoting +
indentation to the line in which the selection ends, but this is wrong,
so nano does add it. Also, Pico doesn't account for partial quoting +
indentation at the start or end of a selection, but this is wrong, so
nano does.
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.
