This patch does nothing but reformatting the current text.

Definitely "intension" is a mistake that I didn't spot, I'm adding a
patch to fix that.

About the paragraph split, I have no strong opinion but I'm feeling OK
with the current layout. It splits the generic statement from the
example and IMHO helps readability. Feel free to send a patch to change
that though, if you think it is useful.
