Method printing takes up too much whitespace in 0.4

[jakebolewski]

seems to be a regression in the array display code as the output is not truncated

compare 0.3

I get an error on 5f3bd18

@mauro3 methodswith was just fixed a few hours ago, so you need a supernew build.

[pao]

Sorry @mauro3 -- not actually fixed yet. See #11052 and 847152d.

[mauro3]

Yes, now I get it too. I guess the issue was filed before it was an issue!

[mauro3]

Actually this seems to sometimes occur with methods as well, for instance methods(*, (AbstractArray, AbstractArray)) but not methods(sin, (FloatingPoint,)) or methods(sin).

[jayschwa]

When a matrix is printed, all elements seem to be padded out to match their longest peer. When one element is long enough that it wraps across the screen, it happens everywhere. The padding should probably be capped to the terminal width or something.

This was intentional: ce23174#diff-b4267643a238b5a375b3e055817ee6caR1474

[tkelman]

the excess spacing is wasteful and we should fix it
