I think the issue here is that the original case for this is a user 
accidentally getting into an \if and then having no clue what's going 
on. That's similar to what happens when you miss a quote or a semicolon. 
We handle those cases with %R, and I think %R needs to support if as well.

Perhaps there's value to providing more info (active branch, etc), but 
ISTM trying to do that will just confuse the original (%R) case.
