[Po Lu]

branch: master
commit 4cb3b4e98a7c43de9e210c22f70e9ad323a4340e
Author: Po Lu <luangruo@yahoo.com>
Commit: Po Lu <luangruo@yahoo.com>

    Fix wrong source window being generated for XDND leave events
    
    * src/xterm.c (x_dnd_update_state, handle_one_xevent): Let
    x_dnd_last_seen_toplevel remain at its old value until any
    XdndLeave event was definitely sent.
