add -C/--colors: dumps all available colors

optimization: don't endwin() when we can simply move the windows After a resize we should do the endwin+refresh+clear dance, but in other situations, like when entering the minibuffer, we can simply re-wrap the page and move the windows. This prevents a small flash when entering the minibuffer, as well as fewer redraw (redraw after the command and shortly after because it was scheduled).

refactor struct vline the new `meta.data' field will be useful for holding completions data.

disentangle the minibuffer and olivetti-mode

wrap long line

support completions in minibuffer + related interactive fns * cmd.c (cmd_previous_completion): add previous-completion (cmd_next_completion): add next-completion (cmd_insert_current_candidate): add insert-current-candidate * minibuffer.c (enter_minibuffer): support completions in minibuffer

finally start this completion-read

simplify conditionals

handle gracefully really small windows (< 15 lines)

foreshadowing: the "real" completing_read

tweak the handle_resize_nodelay logic

move defaults.c decls. to their own header

completing_read: take tab pointer instead of id

typo + fmt

factorize place_cursor
