Overly "compressed" display

[Scott Jones]

I ran into the following:

julia> d
Dict{UInt128,Int16} with 188 entries:
  0x0000ffffffffffff0000f… => 123
  0xffffffffff7fff3dfffff… => 61
  0xfffffffe027ffffffffff… => 13
  0xfffffffffffcfffffffff… => 181
  0x00000000000007fffffff… => 113

where whatever is being used to display the dictionary is unnecessarily truncating the display of the key...

1) I'd like to know what code is responsible for this display (so that I might fix it at some point)

2) *If* people agree with me that the current display isn't very helpful...

It would be good to improve this – in particular, not eliding output when there is room to print the entire output would be good. This is kind of involved and I've lost track of where this code is, but you can start to follow the breadcrumbs with @edit show(STDOUT, d).

Yes, this could definitely be improved.  The relevant section is here: https://github.com/JuliaLang/julia/blob/eb5da264e87f24a091966ecca266b3568aaf7a10/base/dict.jl#L86-L125

Right now it uses (up to) one third of the screen for the key, and the remainder for the values.  That should be changed to be more flexible.
