Documentation

What to do with the debugger buffer when exiting debug.

The value affects the behavior of operations on any window previously showing the debugger buffer.

nil means that if its window is not deleted when exiting the
  debugger, invoking switch-to-prev-buffer will usually show
  the debugger buffer again.

append means that if the window is not deleted, the debugger
  buffer moves to the end of the window's previous buffers so
  it's less likely that a future invocation of
  switch-to-prev-buffer will switch to it. Also, it moves the
  buffer to the end of the frame's buffer list.

bury means that if the window is not deleted, its buffer is
  removed from the window's list of previous buffers. Also, it
  moves the buffer to the end of the frame's buffer list. This
  value provides the most reliable remedy to not have
  switch-to-prev-buffer switch to the debugger buffer again
  without killing the buffer.

kill means to kill the debugger buffer.

The value used here is passed to quit-restore-window.

This variable was added, or its default value changed, in Emacs 24.3.
