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.

Regression test for updates which conflict with an existing ability constructor
https://github.com/unisonweb/unison/issues/2786
First we add an ability to the codebase.
Note that this will create the name Channels.send
as an ability constructor.
unique ability Channels where
send : a -> {Channels} ()
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`:
ability Channels
scratch/main> add
⍟ I've added these definitions:
ability Channels
Now we update the ability, changing the name of the constructor, but, we simultaneously add a new top-level term with the same name as the constructor which is being removed from Channels.
unique ability Channels where
sends : [a] -> {Channels} ()
Channels.send : a -> ()
Channels.send a = ()
thing : '{Channels} ()
thing _ = send 1

do an `add` or `update`, here's how your codebase would
change:
⍟ These new definitions are ok to `add`:
Channels.send : a -> ()
thing : '{Channels} ()
⍟ These names already exist. You can `update` them to your
new definition:
ability Channels
These should fail with a term/ctor conflict since we exclude the ability from the update.
scratch/main> update.old patch Channels.send
x These definitions failed:
Reason
term/ctor collision Channels.send : a -> ()

scratch/main> update.old patch thing
⍟ I've added these definitions:
Channels.send : a -> ()
thing : '{Channels} ()
⍟ I've updated these names to your new definition:
ability Channels
If however, Channels.send
and thing
depend on Channels
, updating them should succeed since it pulls in the ability as a dependency.

sends : [a] -> {Channels} ()

Channels.send a = sends [a]
