[igraph] neighborhood

[Matt]

Dear all,

I was wondering if something change in the neighborhood function.
In an old code that ran smoothly with this function I am experiencing
some problems.

For example, I remember that in order to count the number of vertices
in a neighborhood EXCLUDING the vertex I was analyzing, I had to
subtract 1 because neighborhood function returned the number of
vertices INCLUDING the vertex whose neighbors I was interested in.

Now I find that if I subtract 1 I have vertices with out-degree 2 I
get a neighborhood of 1 (computed considering just the out-edges).

Is the neighborhood function returning the neighbors without the
"starting" vertex now?

Thank you very much in advance for your help.

Cheers.

Matt
