Hmm. You are right. This only gives a syntax error inside a 'do...'
block. And now as I think about why this is the case, I can't see a
good way to fix it, other than giving if/then/else-completion a higher
precedence than layout. Hmmmm.
Arguably this would be the right behavior. The if/then and then/else
pairings in effect unambiguously bracket the predicate and alternative
respectively, and oughtn't cause a problem with layout.
