When we were saving message history as part of a game save for insurance,
we were calling remember_topl() and thus inappropriately changing topline
state. This would cause us to mis-manage the topline in subsequent calls
to update the topline.
The code has been re-worked to fix the issue, reduce complexity and make
the code clearer.
When we save gamestate as part of making an insurance snapshot, we will
save message history which will clear toplines but leaving window state
in tack including the need for more.
When fuzzing, we would increment ttyDisplay->inmore but then prematurely
exit more() leaving ttyDisplay->inmore set.
Under various conditions, we can request to remember the topline when
the topline had not yet been acknowledged leaving toplin state in an
inappropriate state.
Highlighting via attributes got broken three months ago. May or
may not have been noticeable depending upon which attributes are
supported. Too many variations of attribute designations...
Messages on tty which bypass message history weren't handling long
lines properly. If the text wrapped to line 2, that continuation
portion was left on the screen after whatever operation that put it
here was finished. (To reproduce: assign a long name to a monster
with a long type name so that the combined length exceeds the display
width, then move the cursor over it with ';' or '/' while autodescribe
is On.)
This time prompting isn't adversely affected.
This effectively reverts 1ad2415315
because it was interfering with prompts that spanned more than one
line (by inserting '--More-- + erase' between displaying of prompt and
getting input for the answer).
So we're back to the situation where autodescribe feedback when moving
the cursor will leave text on the second line if it generates text too
wide for one line. (^R redraws the screen correctly.)

The earlier fix removed a valid optimization which happened to be
implemented incorrectly. Put that back. It also left an invalid
optimization when applied to conditions. Remove that one.
I don't think either of these explains truncating 'y' off of "Hungry"
which was shown in one of the reports.

Some code recently added to render_status() for BL_CONDITION:
if (!tty_condition_bits)
continue;
was short-circuiting the required copy of NOW
values to BEFORE values for later comparison
further down in the for-loop.
tty_status[BEFORE][idx] = tty_status[NOW][idx];
This caused some fields to be bypassed for rendering
once no more tty_condition_bits were set because the
length comparisons would match.
