Functions are not labelled with the `std::` prefix

Hi!

We are using XML tag file integrated with Doxygen so we can do things like:

/// @see std::vector

This works great for classes and structs, but not for functions, because in the XML tag file the <name> section does not include the std:: prefix, so we need to write:

/// @see begin

Instead of:

/// @see std::begin

Why is that? Would it be possible to add the std:: prefix to all symbols?

This sounds like something worth contributing upstream 🤔
