Thanks for pointing out this idiom.

Meanwhile, I have discovered that Boost.Algorithm's any_of and any_of_equal:

http://www.boost.org/doc/libs/1_55_0/libs/algorithm/doc/html/the_boost_algorithm_library/CXX11/any_of.html

work with ranges out of the box, eliminating the need to use find or 
find_if for this purpose.
Note also that there is also a contains() to test whether a range is 
contained, buried in <boost/algorithm/string/predicate.hpp>.
Perhaps these should be presented in the documentation instead?
