Reporting wrong line numbers

$ git todo origin/master
ring/ingester_lifecycle.go:3:
  // TODO(jml): Change this to a metric.

ring/ring.go:3:
  // TODO(jml): Do we already have metrics for this? If so, just delete
  // this. If not, add some!

Shouldn't be 3, but rather 151 and something else not 3.
