As there’s no C++ runtime any more there’s really no point in having anything but Rust tags being made.
I’ve also taken the liberty of excluding the compiler parts of this in the `librust%,,` pattern substitution. Whether or not this is “correct” will depend on whether you want tags for the compiler or for general use. For myself, I want it for general use.
I’m not sure how much people use the tags files anyway. I definitely do, but with Racer existing the tags files aren’t quite so necessary.
