anacron: line continuation character in anacrontab

[David M]

Does anybody know what the line continuation character in anacron's 
anacrontab file is supposed to be?

man anacrontab (Ubuntu 6.10) says:

    You can continue a line onto the next line by ending it with a ’´.
 
Is there supposed to be a character between the two quote marks?
I've tried both using both the 'quote' and the `backquote` characters as 
the continuation character, but neither seems to work.

David.
