[pr2eus_tutorials] Fix publish status

[shmpwk]

During pr2eus_tutorials, robot status is showed on rviz.
Previously, it only shows "click tabletop object in image_view2! though we can click both on rviz and on image_view2.
So I've changed the showing status
from

to

[k-okada]

(defun publish-info (&rest args)
  (let ((s (format nil (car args) (cdr args))))
    (ros::ros-info s)
    (publish-status 'info s)))

publish-info calls both ros::ros-info and 'publish-status, so why you need to call ros::ros-info` twice?

[shmpwk]

You're right. (I forgot why I don't use publish-info)

[shmpwk]

This is because

(ros::ros-info  (format nil "click tabletop object~%in Rviz or in image_view2!"))

called by

(publish-info (format nil "click tabletop object~%in Rviz or in image_view2!"))

splits the sentence on the command line, which is slightly difficult to read.

[k-okada]

may be (format nil "click tabletop object~%in Rviz or in image_view2!") seems simpler

Thank you for your advice, I improve it.
