This PR changes the "declaration uses 'sorry'" warning to use backticks instead of single quotes, consistent with Lean's conventions for formatting code identifiers in diagnostic messages.

When `warn.sorry` is false, don't log the "declaration uses `sorry`" warning.

Synthetic sorries should come with associated errors.
|
|
We want to get an error if there is a synthetic sorry with no associated error.
|
|
However: sometimes there are synthetic sorries in terms that come from other other terms
|
|
that have already been warned about. There is no way to tell if a given synthetic sorry had
|
|
been reported on previously. We want to be able to turn off the warning in this case too.
|
|
If we can tell whether sorries have already been warned about,
|
|
we could direct the user to inform us about elaboration bugs (synthetic sorries with no errors in the message log).
|
|
|
|
So, for now we report them just like a user `sorry`.
