Indeed, auto-indent in Python makes about as much sense as
auto-write-my-whole-program.

In C++, I would simply wrap the block in an "if" with its curly braces, and then auto-indent using Vim's "%" curly brace matching command and the "=" auto-indent command.

Vim really doesn't suck for Python.  I use shift-v and > to indent a
block and shift-v and < to dedent.  How is this any harder than going
and adding the close brace?  The hard part is figuring out where your
block ends, and you have to do that in any editor.
