Typically, pointer types are formatted in a way where the identifier comes right after the type definition without a space separating them, e.g.
int *foo, where the type isint *and the identifier isfoo. However, if a type alias to a pointer type is used, the emitted declaration fragments are incorrect due to the missing space between the type and identifier, like in the below example:This patch checks if pointer types are aliased, and inserts the space correctly if so.
