Changes (by vbraun):

 * status:  new => needs_review


Old description:

> The doctests output should look like the Sage commandline output, which
> it currently does not quite. Differences include:
> * Dictionaries will be sorted by key, makes output more reproducable
> * Sets are printed as `{1,2}` instead of `set([1,2])`
> * Empty set is `set()` instead of `set([])`
> * Types are `<Foo at 0x...>` instead of `<Foo object at 0x...>`

New description:

 The doctests output should look like the Sage commandline output, which it
 currently does not quite. Differences include:
 * Dictionaries will be sorted by key, makes output more reproducable
 * Sets are printed as `{1,2}` instead of `set([1,2])`
 * Empty set is `set()` instead of `set([])`
 * Types are `<Foo at 0x...>` instead of `<Foo object at 0x...>`

 Other changes:
 * Normal tracebacks can now be distinguished from tracebacks in `__repr__`
 (IPython extension):
 {{{
 sage: f(*args)
 <repr(<sage.interfaces.gap.GapElement at 0x...>) failed: ValueError: The
 session in which this object was defined is no longer running.>
 }}}
 * Plots now print themselves in doctest mode:
 {{{
 sage: A.plot()
 Graphics object consisting of 1 graphics primitive
 }}}
