Display for CuArray within Tuples does not respect :limit=>true

[denizyuret]

Displaying a large CuArray at REPL uses :limit=>true:

julia> a
a
3×20 CuArray{Float32,2}:
 0.170696  0.931874    0.279238  0.935198  …  0.755874  0.25591   0.145203  0.109953
 0.55215   0.730604    0.519178  0.861671     0.606171  0.445813  0.349833  0.0233826

However when the array is in a tuple, this doesn't work, which is an issue with very long arrays (weight matrices in DL models etc):

You probably have:

julia> Base.active_repl                                                                                                                              
REPL.LineEditREPL(...)

This problem occurs when (e.g. in emacs shell):

julia> Base.active_repl
REPL.BasicREPL(...)

[maleadt]

Still works:

[denizyuret]

OK, I think I figured it out, I think this only happens in emacs shell because it uses the dumb terminal, try:
TERM=dumb julia

[maleadt]

That's exactly what I did to get the BasicREPL, and it still worked properly.

[denizyuret]

OK, that's odd. Here is what I get on several linux machines I tried. We could have different linux versions, different julia versions, different startup files, different terminal settings?

 [dyuret@login02 ~]$ TERM=dumb julia --startup-file=no
