Patch attached. The reverse predicate doesn't add any significant functionality, and complicates the implementation, so I removed it entirely. Since iter_fold_if with a reverse operation doesn't work currently, this shouldn't break existing code.

Please ignore attachment, while_recur.2.cpp. It's just an accidental copy of while_recur.cpp.

While_recur.cpp is essentially the while.cpp attachment with template, while_recur, as a renamed while_ of the while.cpp attachment. ALso while_recur.cpp has the while_unroll_recur template which is an "unrolled" (to lessen the template instantiation depth problem mentioned in comments) version of while_recur. The macro, USE_WHILE_UNROLL, decides whether while_recur or while_unroll_recur is used.
