When backspace is received at the beginning of a line and the previous line was
...
wrapped, move the cursor back up to the end of the previous line.
Another one of the forgotten persons requested this quite a while ago (I need
to start noting names on todo items...) when it was quite hard to
implement. Now it is easy and I don't see it can do any harm, so hey presto...

Instead of just checking for an empty buffer, which may not be the case if
...
there is unconsumed data, save the previous size and use it instead. This means
that activity monitoring should work in this (unlikely) event.
Also remove a debugging statement that no longer seems necessary.

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.

Using the alternative screen (smcup/rmcup) should also preserve the current
...
colours and attributes. Found thanks to a report from Taylor Venable.
While here also nuke a couple of extra blank lines.

Make some functions which return unused values void (mostly found by lint) and
...
tweak a redundant expression in window_pane_set_mode.

Support "alternate screen" mode (terminfo smcup/rmcup) typically used by full
...
screen interactive programs to preserve the screen contents. When activated, it
saves a copy of the visible grid and disables scrolling into and resizing out
of the history; when deactivated the visible data is restored and the history
reenabled.

Proper support for tab stops (\033H etc), using a bitstring(3). Makes another
...
vttest test happy.

Okay, so I screwed up when testing this, doh. Unbreak so that CAN/SUB actually
...
do cancel the sequence, and tweak to make the code more clear.

Oops, CAN and SUB should abort the sequence (return to first state), not remain
...
in the same state.

More input compatibility love. Support C0 within escape sequences, and the C0
...
control character VT (vertical tab, \013), which is treated as LF like
VT102. Makes another vttest happy.

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.

Pass window titles through vis(1). <0x20 is dropped anyway by the input state

machine but top-bit-set nonprintables could cause trouble, and they are neater
like this anyway.
Suggested by deraadt a few days ago.
