I would like to see pprint be smarter about printing lists and dicts. At 
the moment, a long list is either printed all on one line, like the 
default display, or one item per line. This can end up as one long, 
narrow column, which is worse than the default. I'd like to see it be 
smarter about using multiple columns.

E.g. pprint([1, 2, 3, ... 1000])

rather than this:

[1, 
 2, 
 3, 
 ...
 998,
 999,
 1000]

something like this:

[1,    2,    3,    4,    5,    6,    7,    8,    9,   10,
 ...  
 991,  992,  993,  994,  995,  996,  997,  998,  999, 1000]
