exa -G not respected

[Squirreljetpack]

When piping exa -G | head -n 4, the output of exa is in one line mode
When running COLUMNS=4 exa -G, the output of exa is in one line mode
This differs from ls ls -C --color=always | head -n 5 which works as expected

EDIT: Seems ls has some trouble with this as well. It can only do 2 columns.
I suppose this has turned into a feature request: can we have an option to limit the number of items shown?

I bisected this to af20828:

$ git bisect bad

    Update term_grid to 0.2

That commit reverts cleanly today (on c697d06), if anyone wants a quick fix.

I'll try to bisect within term_grid itself if I can.

I think this is caused by ogham/rust-term-grid#11, and fixed by ogham/rust-term-grid#12. (I haven't looked at the code at all, but applying the PR makes exa display grids properly again.)

...apparently this was already found two years ago in #990...

This is already fixed in master and in the active fork exa.
