show current definition being edited

This serves two purposes:
- Things get confusing if function being defined doesn't match the
  definition name. Displaying the current definition helps diagnose this
  situation.
- We're already able to see callers at a glance even if the cursor is
  below the fold. The name of the current definition is arguably more
  important in that situation.
