Ormolu forcing long lines in function definitions

[sellout]

Describe the bug
In a function definition,

foo bar =
  body

foo bar = is beyond our auto-enforced line length, but Ormolu doesn't let me break it, AFAICT. Every variant I try has Ormolu suggesting foo bar = on a single line.

To Reproduce
Define a function with a single argument, and try to get it to not put everything on one line.

Expected behavior
There should be some way to separate these tokens. My suggestion would be something like

foo
  bar
  = body

I.e., treat = more like an operator.

Environment

• OS name + version: NixOS 20.03
• Version of the code: 0.3.1

I guess the more obvious formatting would be to match the same behavior on multi-param functions ...

foo
  bar =
    body
