Subject: Watch for empty response when getting current line.

- When we query the current line from the terminal, there
  are situations when that might time out and yield a blank
  response. In basta.check_cursor, we guard against that, or
  else the user may, rarely, see a message complaining that
  the [ command is missing an operand for the -gt operator.
