Automatically generated doc is not correct

In some points, there is some documentation generated automatically by some macro, that is not perfectly correct. A human should be able to see the meaning, but it can generate confusion at a first reading.
See for example https://nalgebra.org/rustdoc/nalgebra/base/struct.Matrix.html#method.sub_to. The doc says that the operation is equal to `self + rhs` while in fact it should perform `self - rhs`.
