My preference is to not do this until a need has been demonstrated, but
this sounds like it could be useful one day. I'll review the patches
from the viewpoint that we do want this feature.

This sounds like a good idea. "Trust" is probably too strong a word, but
I can see this being useful even in non-whitespace-sensitive languages
with nested blocks (like C).
