Add a space before code block info strings 
This is for consistency with the `cmark` style. Now the blocks we still
pretty-print ourselves will match the bulk of them that `cmark`
produces.

Ensure type dependencies are properly considered in slurping

https://github.com/unisonweb/unison/pull/2821

Define a type.

structural type Y = Y

Now, we update Y, and add a new type Z which depends on it.

structural type Z = Z Y
structural type Y = Y Nat


  Loading changes detected in scratch.u.

  I found and typechecked these definitions in scratch.u. If you
  do an `add` or `update`, here's how your codebase would
  change:
  
    ⍟ These new definitions are ok to `add`:
    
      structural type Z
    
    ⍟ These names already exist. You can `update` them to your
      new definition:
    
      structural type Y
        (The old definition is also named builtin.Unit.)

Adding should fail for BOTH definitions, Y needs an update and Z is blocked by Y.

scratch/main> add 

  x These definitions failed:
  
    Reason
    needs update structural type Y
    blocked      structural type Z
  
    Tip: Use `help filestatus` to learn more.

-- This shouldn't exist, because it should've been blocked.
scratch/main> view Z
