Never mind the second half of my comment, the issue has nothing to do with
irreflexivity of course.

The point is, in the implementation of std::min the comparison fails and the
first argument is returned, because the standard wants the first argument if
the arguments are equivalent. Given the latter requirement + only
LessThanComparable is required, I don't see how the behavior could be
different.
