[Doug Evans <xdje42 at gmail dot com>]

Hi.

fyi, I committed this cleanup to cli-script.c.
Regression tested on amd64-linux.

2013-11-23  Doug Evans  <xdje42@gmail.com>

	* cli/cli-script.c (multi_line_command_p): New function.
	(recurse_read_control_structure, read_command_lines_1): Call it.
	(execute_control_command): Consistently have a blank line between
	each case.
