-- Use label instead of text if text has different starting characters.
-- label is used as abbr (=displayed), but word is used for filtering
-- This is required for things like postfix completion.
-- E.g. in lua:
--
-- local f = {}
-- f@|
-- ▲
-- └─ cursor
--
-- item.textEdit.newText: table.insert(f, $0)
-- label: insert
--
-- Typing `i` would remove the candidate because newText starts with `t`.
