function::indent_depth - returns the global nested-depth

delta
           the amount of depth added/removed for each call

       This function returns a number for appropriate indentation, similar to indent. Call it with a small
       positive or matching negative delta. Unlike the thread_indent_depth function, the indent does not track
       individual indent values on a per thread basis.
