  matrix lines of highlighted text to become EQ?.

* (with-screen-in-update): Eliminate UNWIND-PROTECT since interrupts
  are locked while it executes and any errors in the redisplay
  indicate a serious problem that makes the UNWIND-PROTECT
  uninteresting.

* (with-screen-in-update): Avoid calling SCREEN-UPDATE if the screen's
  NEEDS-UPDATE? flag is not set.

* (with-screen-in-update, screen-update): Don't update the cursor
  position unless the screen update finishes and the cursor has moved.

* (screen-update): Avoid use of FIX:REMAINDER, which is not open-coded
  on the MIPS.

* (screen-update): Change meaning of PREEMPTION-MODULUS so that it
  counts the number of updated lines rather than the number of lines.
  This avoids unnecessary work when only a few lines need changing,
  such as when only the modeline or typein window is being updated.
  Because of this change, eliminate DEBUG-PREEMPTION-Y from the SCREEN
  structure since it is no longer easy to simulate preemption like
  this (and this debugging tool was never needed).

Chris Hanson [Fri, 13 Mar 1992 10:05:26 +0000 (10:05 +0000)]
COMINT-LINE-START was matching COMINT-PROMPT-REGEXP against the
remainder of the buffer when it is only necessary to match against the
remainder of the line.  This occasionally caused the primitive
re-match-buffer to signal an anonymous error.  This patch
will make the anonymous error extremely unlikely.

The anonymous error indicates a stack-overflow condition that is
difficult to fix properly.  However, the primitive can be modified to
use heuristics that will eliminate the error; the cost is that cases
that would have signalled the error will instead return a non-maximal
match or a non-match in cases where it would have returned a maximal
match had the stack been deep enough.
