add M-t (tab-select); extend the completion API

reload-page and bindings

bind < to load-current-url

bind <up> and <down> for completion instead of history <up> and <down> are now bound to previous/next-completion instead of previous/next-history-item

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

bind and advertise B/F for previous/next-page instead of C-M-bf/b

refactor: all imsgs are completely asynchronous

bugfix: allow editing minibuffer history restore the current line, so the editing operations can actually modify the input buffer, instead of the history string.

fix certificate mismatch after load_previous_page and proxy load_previous_page calls directly do_load_url, where the proxy reset happens in load_url.

sync

bind C-w to tab-close by default

bind c-t to tab-new by default and while there document some missing keys.

re-exec the children processes This way, they get their own new random address space.

bugfix: print the trailing face until the right column This would leave the last column white if !olivetti-mode and a background color for some body lines

fix detection of empty lines inside pre blocks empty lines inside pre blocks were misleadingly matched as LINE_TEXT.
