Patch #1542451: disallow continue anywhere under a finally
I'm undecided if this should be backported to 2.5 or 2.5.1.
Armin suggested to wait (I'm of the same opinion). Thomas W thinks
it's fine to go in 2.5.

+Test continue in finally in weird combinations.
+
+continue in for loop under finally shouuld be ok.

+ ... try:
+ ... pass
+ ... finally:
+ ... for abc in range(10):

+ ... print abc

+
+Start simple, a continue in a finally should not be allowed.

+
+This is essentially a continue in a finally which should not be allowed.
