Ugh, committed the wrong version of this change and got both solutions rather
than just the second. Remove unused assignment.

A few trivial optimisations: no need to check for zero size if calling
buffer_ensure in buffer.c; expand grid lines by a greater increase than one
each time; and don't read UTF-8 data unless it actually needs to be checked
when overwriting a cell.

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.

664a0bd559 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.

e073441c36 Tidy by removing unused argument from grid_view_{insert,delete}_line_region
functions (currently don't fully work, this is to make fix easier).

35092835b0 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.

de2ea2d178 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.

93631b3ca7 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.

to the cursor is cy not cy - 1, and the current cursor cell should be included.

1e06ec41dc Add a UTF-8 aware string length function and make UTF-8 in
status-left/status-right work properly. At the moment any top-bit-set
characters are assumed to be UTF-8: a status-utf8 option to configure this will
come shortly.

4cbf7d489e - Ignore padding when writing so copying the screen for copy-mode doesn't include extra characters.
- Handle combined characters properly when the previous character is not UTF-8.

cf7b384c43 Better UTF-8 support, including combined characters. Unicode data is now stored
as UTF-8 in a separate array, the code does a lookup into this every time it
gets to a UTF-8 cell. Zero width characters are just appended onto the UTF-8
data for the previous cell. This also means that almost no bytes extra are
wasted non-Unicode data (yay).

Still some oddities, such as copy mode skips over wide characters in a strange
way, and the code could do with some tidying.

6c0728fe07 Step 2 of the Grand Plan To Make UTF-8 Better.
Split grid into two arrays, one containing grid attributes/flags/colours (keeps
the name grid_cell for now) and a separate with the character data (called
text). The text is stored as a u_short but is treated as a uint64_t elsewhere;
eventually the grid will have two arrays.

I'm not happy with the naming so that might change.

Still need to decide where to go from here. I'm not sure whether to combine
the peek/set functions together, and also whether to continue to treat the
text as a uint64_t (and convert to/from Unicode) or make it a char array
(of size one when UTF-8 disabled, eight when enabled) and keep everything
as UTF-8.

Also since UTF-8 will eventually become an attribute of the grid itself it
might be nice to move all the padding crap into grid.c.

Nicholas Marriott
514fe11727 We are going to need the updated screen data for emulating the scroll region,
which may involve changing the cursor position; however, the old (before
redraw) cursor position is necessary for writing to the tty. So, save it before
doing the redraw then update the internal screen then update the tty.

Not sure I like this solution but it does the job for now.

4428987e95 * Better support for at least the most common variant of mouse input: parse it and adjust for different panes. Also support mouse in window/session choice mode.
* Bring back the fancy window titles with session/window names: it is easy to work around problems with elinks (see FAQ).

cd8f85c2bd When I wrote this I somehow forgot that the cursor could helpfully sit at sx
(one character off the right of the screen), so there are several out-of-bounds issues. Add some additional checking.
