Terser leading/trailing syntax in scm

[AndreasArvidsson]

It's unnecessary having to specify that the leading and trailing ranges should terminate at the content range. We could just specify their distal position and the range could be calculated for us.

from:

  (flow_node)? @collectionItem.leading.start.endOf
  .
  (flow_node) @collectionItem @collectionItem.leading.end.startOf @collectionItem.trailing.end.endOf
  .
  (flow_node)? @collectionItem.trailing.end.startOf

to:

  (flow_node)? @collectionItem.leading.endOf
  .
  (flow_node) @collectionItem
  .
  (flow_node)? @collectionItem.trailing.startOf

@pokey @josharian Any thoughts?
