pretty-printer includes a trailing space on multiline assignments

[ceedubs]

For lines that exceed certain length, the pretty-printer hangs the value onto a new line like this:

response = 
  interruptibly interrupt '(handle tryRequest req with Http.handler)

What might not be obvious from this example is that there is a trailing space after the =. This really doesn't matter, and yet I find myself bothered by it 😅 . In particular this is annoying if your editor warns you about trailing whitespace (which for me seems to be coming from the neovim LSP client).
