12166	multi_pass_iterator comparisons should be const	edaskel@…	Joel de Guzman	"Some, but not all, comparison operators of multi_pass_iterator are const.  Specifically == and < are const, but !=, >, >=, and <= are not.  You can see this [https://github.com/boostorg/spirit/blob/develop/include/boost/spirit/home/support/iterators/multi_pass.hpp#L137-166 here]

This causes compile errors when multi_pass_iterator users try the common (it != end) idiom."	Bugs	closed	To Be Determined	spirit	Boost 1.61.0	Problem	fixed
