I assume this function lets you search for an element starting in the=20
middle of a single-linked list (the middle because you could call=20
`ft_list_find(&p-next, data_ref)` where `p` points to any element in the=20

case the loop body wouldn't run). If so, I don't think this does what's=20
intended. This actually unlinks (and memory-leaks) elements up to where the=

match is found. I think you want to advance `start_list` this way (I didn't=

test this):
```
start_list =3D &(*start_list)->next;
