API on_state for Vim Mode change of statusbar

I checked that on_state is fired when ALL statusbar cells are inited. this code always shows ‘info-here: True’.

    def on_state(self, ed_self, state):
        if state==APPSTATE_CONFIG_REREAD:
            h = app_proc(PROC_GET_MAIN_STATUSBAR, '')
            index = statusbar_proc(h, STATUSBAR_FIND_CELL, value=20)
            print('cfg reread,', 'info-here:', index is not None)

so why do you need to check that statusbar is fully inited? it must by fully inited always if you get APPSTATE_CONFIG_REREAD

try without my patch: if you make vim mode persistent and restart Cud, you will see that statusbar is not fully painted in vim-mode color, but vim-mode is enabled. even on “session loaded” event statusbar is not ready yet. at least on my OS (Windows).

APPSTATE_CONFIG_REREAD is not happening on start. (is it happening on linux?) APPSTATE_API_SUBCOMMANDS is happening on start (not on clean Сud though)

we need some event that will occur on start but when all is settled. so we can paint all statusbar cells on startup.
