+** New 'flex' completion style
+An implementation of popular "flx/fuzzy/scatter" completion which
+matches strings where the pattern appears as a subsequence. Put
+simply, makes "foo" complete to both "barfoo" and "frodo". Add 'flex'
+to 'completion-styles' or 'completion-category-overrides' to use it.
