My compiler warned about this function. The `dst` and `src` pointers
will equal some random data on the stack, then they may or may not be
assigned to, then we will call `free()` on them.
At least I *think* that we "may or may not" assign to them. I don't have
much or any time to really dig into this right now unfortunately.
I suppose this could use a REFSPEC_ITEM_INIT, or a memset inside
`parse_refspec()`, but I am very unfamiliar with this code.
