Syntax:  CLOSE BUFFER buffer_name

  Writes and deletes a buffer.

  If the specified buffer is writable and has been modified, LSE writes
  it to its associated file, and then deletes the buffer.  If a file is
  not associated with the buffer, LSE prompts you for a file name.  If
  no buffer is specified, the current buffer is used.
