automatic alignment does too much when we have blocks within blocks

[dimbleby]

#105 improved matters, but still left this:

I have to work through the case where

tags = {
  thing = "whatever"
}

because currently it becomes

tags    = {
  thing = "whatever"
}

I don't use the Tabular integration myself and am unlikely to do anything about this, but merge requests that fix it would be welcome!
