This is a line continuation, so it's not good style to indent it at the same level as the previous line. The preferred indentation for a function call is to align it with the other arguments (as it was before the change). If you want, a better style IMHO would be:

```
crypto_util.encrypt(crypto_util.getkey(g.sid), msg,
                    output=store.path(g.sid, filename))
```
