clechoev and resizeev are two globally defined event, and thus guaranteed to be zeroed. While OpenBSD' libevent1 is fine when calling event_pending on such events, libevent2 complains and, probably depending on which flags were used, crashes. Prompted and tested by Andrea Feletto, thanks!

maybe in the future we'll try to handle SIGTSTP?

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).

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

* 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
