There is currently a round-trip problem when running code through ocamlformat and then ocp-indent. Consider code like this:

type t =
  { field : ty
  (* Here is some verbatim formatted text:
     {v
       starting at column 7
     v}*)
  }

If I run it through ocamlformat as of a906b5d, I get the following:

type t =
  { field : ty
        (* Here is some verbatim formatted text:
           {v
             starting at column 7
           v}*)
  }

The whole comment has been indented uniformly, as ocamlformat puts comments on fields farther to the right than that.
Now if I run that result through ocp-indent, I get this:

type t =
  { field : ty
  (* Here is some verbatim formatted text:
     {v
             starting at column 7
           v}*)
  }

Now ocp-indent has moved the comment back to the left. However, because it treates {v ... v} as a verbatim block, it left it indented further to the right.
If I then save this code, and run it through ocamlformat and ocp-indent again, that comment will move several spaces further to the right, and on and on. The process does not have a fixed point.

For our current workflow at Jane Street of using ocamlformat with ocp-indent, I think we need one of (a) consistent comment handling between ocp-indent and ocamlformat, (b) ocamlformat not to move any whitespace within comments, or (c) ocamlformat to offer editor integration so we can drop ocp-indent. Pretty clearly (a) is preferable to (b), and I expect (c) is a much bigger lift, but any of the above will alleviate the immediate problem for us.
