Avoid memcpy'ing NULL pointers
A UBSAN warning can be triggered because the link title is an empty string: src/inlines.c:113:20: runtime error: null pointer passed as argument 2, which is declared to never be null which can be triggered by: ``` [f]:_ [f] ``` The length of the memcpy is zero so the NULL pointer is not dereferenced but it is still undefined behaviour.
