Easy format outputs no margins with width 68

[charlesetc]

This is an edited version of simple_example.ml that prints the same thing 3 times, once with width 67, once with width 68, and once with width 69.

Here's the output:

You can see that the 68 version doesn't have the proper indentation. This was found here: reasonml/reason#446

What a funny bug!

That's strange! Could you provide an OCaml version of the Reason program https://gist.github.com/Charlesetc/42fdd7295bb364ae3ecd77ecc8a9da01 ?

I transformed that via the refmt program into OCaml via the following command:

curl https://gist.githubusercontent.com/Charlesetc/42fdd7295bb364ae3ecd77ecc8a9da01/raw/bd6632cc848260eb1844d5aedbab68c54f7bf688/breaking_margin.re | refmt -parse re -print ml -use-stdin true -is-interface-pp false

And it output:

Thanks @jordwalke - should've posted it in OCaml to start

I am running into this as well, for now i have just setup a switch to change column width of 68 to 67, what a weird bug.

[jordwalke]

Yeah, it's very hard to imagine what could be causing this!
