(un)folded -> (un)fold

[Laurent Martelli]

There are still a few references to the old (un)folded in the
docs. Here's a patch :

refman.itely :

177c177
< @item unfolded  
---
> @item unfold  
185c185
< @item folded  
---
> @item fold

tutorial.itely :

1361c1361
< @cindex unfolded @code{\repeat}
---
> @cindex unfold @code{\repeat}
