[Yuuki Harano]

branch: feature/pgtk
commit d899fc11f6a5f55fdb215ad88b183a75123218ae
Author: Yuuki Harano <masm+github@masm11.me>
Commit: Jeff Walsh <jeff.walsh@drtusers-MacBook-Pro.local>

    Fix tooltips don't hide on events
    
    * src/pgtkterm.c: New variable to indicate whether any event occurs.
    (configure_event): Clear help string on a event.
    (leave_notify_event): Clear help string on a event.
    (motion_notify_event): Use gen_help_event.
    (pgtk_set_event_handler): Hook configure-event for outer widgets.
    (pgtk_term_init): Clear the flag.
