Comment (by ncohen):
> It does that without this branch.
Without this branch (i.e. with beta3) this command opens a window with a
plot:
{{{
sage: show(graphs.PetersenGraph())
}}}
> I'm happy with that if you are.
I am not. `G_{10}` means nothing to somebody in the graph world, and the
previous output was way more informative:
{{{
sage: Graph(4,loops=True,multiedges=True)
Looped multi-graph on 4 vertices
}}}
> I'm only against show() returning something else than the displayhook.
I am against 'show()' returning anything else than what it has been
returning for the last 5 years. You can add a deprecation warning if you
plan to remove 'show()' (I would agree with it), but anything else would
be problematic: you cannot expect `show(g)` to be different from
`g.show()`.
In the meantime, as per our deprecation policy, the result should still be
the same for one year.
There is no reason to consider `show(a_graph) # opens a window` as a bug
either. I consider it as a feature, as do most of the people I talk with.
