Please use the prefix argument, e.g., to control whether to use
a new buffer or not.  I don't want a new buffer for the header
display, so I hope not to change the default behavior.
Furthermore, the `=' command in that new buffer should delete
the buffer and focus on the original buffer again, even if many
buffers have been made randomly before invoking the `=' command,
I think.
