'Assert strip_fors is aware of newlines preceding the current match.
This used to fail because both the postspace for the first closer and
the prespace for the 2nd got 1
added, resulting in 3, which is 1
too many. Now we use the preceding_whitespace function to look behind
and take preceding newlines into account.'
