    if True:
            ^
IndentationError: expected an indented block after 'if' statement on line 1

This fix is ​​to correctly handle the issue of Ctrl+D to exit multi-line mode. What do you think the expected behavior should be?

@ambv FWIW I tested this PR on my Mac (main branch, latest, MacOS latest) and it works great. I tried throwing a bunch of other unclosed constructs (e.g. {, [, etc.) and none exhibited this error either.

@StanFromIreland Are you suggesting that the error message in the if True: case could be more clear?

The fact that the user isn't supplying a valid indented block after the if True: is indeed a problem the language needs to flag, so I'm curious what specific wording you think might be more clear. Also it seems to me like this could be a separate Github issue. Do you agree?
