[igraph] igraph_get_shortest_paths() question

[Paul Melis]

Hi,

I'm currently using igraph_get_shortest_paths() to find a path between 
two nodes. The "from" argument denotes a single vertex, while the "to" 
parameter can contain multiple vertices, including the same vertex 
multiple times. What is the use case for specifying a target vertex 
multiple times? Doing it doesn't seem to return different paths even if 
they exist in the graph (as mentioned in the documentation for 
igraph_get_shortest_paths()).

Thanks,
Paul
