-- A format is a sequence of components; each is either a literal
-- string, or a hledger report item field with specified width and
-- justification whose value will be interpolated at render time.
--
-- A component's value may be a multi-line string (or a
-- multi-commodity amount), in which case the final string will be
-- either single-line or a top or bottom-aligned multi-line string
-- depending on the StringFormat variant used.
--
-- Currently this is only used in the balance command's single-column
-- mode, which provides a limited StringFormat renderer.
