It was originally intended that scroll mode would show content that was
...
currently off-screen due to resize, but somewhere along the way this got
lost. Restore this behaviour to scroll mode by fixing screen_write_copy to read
up to the saved line length rather than the current screen width. Copy mode
remains unaltered for now.

Add a flags member to the grid_line struct and use it to differentiate lines
...
wrapped at the screen edge from those terminated by a newline. Then use this
when copying to combine wrapped lines together into one.

More tty code tidying: move the saved cursor/region position (from before the

screen was updated) out of struct screen and into struct tty_ctx.

enum tty_cmd is only used as an index into the array of command function
...
pointers, so remove it and use the function pointers directly to represent
themselves.

There are relatively few arguments to tty_cmd_* functions now, so tidy them up

by using a struct rather than hiding everything with varargs.

tty_cmd_raw is only used once, for raw UTF-8 output, so rename it to
...
tty_cmd_utf8character and eliminate the size argument.

The scroll region cannot be one line only, ignore attempts to make it so.

Cursor up and down should be limited by the scroll region (cuu should stop at
...
the scroll region top if starting from below it and cud stop at the bottom if
starting from above). Fixes another vttest test.

Change inserting and deleting lines inside the scroll region to properly clear

lines that should be inserted/deleted but not moved. Fixes problems with mutt
reported by Brian Lewis, thanks.

Tidy by removing unused argument from grid_view_{insert,delete}_line_region

functions (currently don't fully work, this is to make fix easier).

Fix two errors with character/line insertion and deletion: the maximum number
...
of characters which may be inserted or deleted is the screen width, not one
less (and similarly for lines and height); and if characters or lines are
deleted by moving the ones that follow, the space at the end needs to be
cleared.
This appears to solve long-standing redraw issues most visible when using the
force-width option then scrolling in view(1) or unwrapping lines in emacs.

Status line fixes: don't truncate status-right now the length calculation is

done for UTF-8, limit to the maximum length correctly when printing, and always
print a space even if the left string is longer than the width available.

Implement the DEC alignment test. With the last change this is enough for the

first cursor test in vttest (in ports) to pass; it still shops a few more
problems though.

status-left/status-right work properly. At the moment any top-bit-set
