Multi-line edit executes too early with await

[cdeil]

I was trying to type this example in IPython:

from prefect.client import OrionClient

async with OrionClient() as client:
    deployment = await client.read_deployment_by_name("Addition Machine/my-first-deployment")
    flow_run = await client.create_flow_run_from_deployment(deployment)

However, typing ENTER after the first line with an await statement stops the multi-line edit too soon and executes the code:

In [16]: async with OrionClient() as client:
    ...:     deployment = await client.read_deployment_by_name("Addition Machine/my-first-deployment")

In [17]:

I think this is a general bug with await, the same bug happens with any other example, e.g.

In [17]: with open():
    ...:     spam = await Thing()

@minrk - related to #13348 ?

I don't think it's related to #13348, which has to do with running async code. This would be in the check_complete check of the input transformer, which considers invalid syntax to be 'complete' so it shows you a syntax error immediately. A top-level await is not valid Python syntax, but IPython manages this during execution by wrapping it in a coroutine. The same wrap doesn't occur in the input-transform check, however, so there's a disconnect between what code is actually run vs what is evaluated for completeness/syntax validity.
