Done and pushed.

Notes:

• The heading for [range.comparisons] seems ugly. For the algorithms, we always quote the namespace in the "itemdecls" when we refer to the ranges stuff, but here we don't. The heading is the only hint that we're talking about the stuff in the ranges namespace, not the stuff in the std namespace. That seems lacking.

From a more global perspective, maybe we want to establish a convention that we use qualified _declarator-id_s for itemdecls talking about stuff in a sub-namespace of std? After all, itemdecls are "definitions", which C++ allows to declare in an enclosing namespace. And for each thing mentioned in an itemdecl, we should already have a declaration somewhere in a header synopsis, which shows the full namespace nesting. @zygoloid?

Filed #2512 to add the ranges:: prefixes on these declarations.
