Actually, I am wrong, there is a spot in ada-lang.c:

      lookup_name_info name1 (std::string ("<_ada_") + name + '>',
			      symbol_name_match_type::FULL);

What's concerning is that this compiles even without the && overload,
presumably by just violating the lifetime requirement of lookup_name_info.

So, I think leaving the && version in-place is best.

Tom
