Yes, that would be ideal. Unfortunately, not every tree expression
node has a location stored for it, so implementing the underlined range
might be tricky to do. (in particular, INTEGER_CST doesn't. I hope to
look into that for gcc 7, perhaps with a wrapper node to provide
locations for expr nodes that don't have them).

Agreed.
