Re: [v3] Document implementation-defined bucket counts

[François Dumont <frs dot dumont at gmail dot com>]

    I hadn't notice that default bucket count for range constructors 
was 0. That's surprising as the equivalent on internal _Hashtable type 
is 10 like for the other constructors. Why not generalizing to 10 ? The 
advantages would be:
- doc simplification
- constructors consistency

    0 is also surprising for a container that has such an important 
memory overhead that creating it to store 1 or 2 elements looks like 
using a tank to kill a fly.
