patch 8.2.1726: fuzzy matching only works on strings Commit: https://github.com/vim/vim/commit/4f73b8e9cc83f647b34002554a8bdf9abec0a82f Author: Bram Moolenaar <Bram@vim.org> Date: Tue Sep 22 20:33:50 2020 +0200 patch 8.2.1726: fuzzy matching only works on strings Problem: Fuzzy matching only works on strings. Solution: Support passing a dict. Add matchfuzzypos() to also get the match positions. (Yegappan Lakshmanan, closes #6947)
