forked from PsychoticNinja/irssi
76c6e9ab83
separately now). Added statusbar code to available to perl, it's now possible to create new statusbar items with perl scripts. statusbar_items_redraw(char *name) can now be used to easily redraw all named statusbar items in screen. Probably several other changes I've already forgotten :) git-svn-id: http://svn.irssi.org/repos/irssi/trunk@1861 dbcabf3a-b0e7-0310-adc4-f8d773084564
