" printf_fmt.vim — printf() conversion specifiers (strings.c/vim_snprintf):
" %d/%x/%X/%o/%b integer radices, flags (0, -, +, #), field width and precision,
" %e/%f/%g float forms, %s/%c, the %% literal, '*' width from an argument, and
" N$ positional arguments. printf returns a String. Self-test: asserts into
" v:errors, throws if any failed.
