julia> n = ["aaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaaa",

3-element Array{ASCIIString,1}:

I've seen this with arrays of Dicts as well.

I see this at the repl, but not in IJulia.

I followed the code calls to print_matrix which calls A=alignment(...), then calls print_matrix_row with A as an argument. alignment decides how much space each element get, and they all get the same amount of space.

Seems related to #5709.

ggggggggg's explanation makes sense.

[tkelman]

This was also the cause of #11056, and I think we should revisit the "all get the same amount of space" part of this as it leads to a lot of wasted space and ugly output in many situations.
