Don't blame Petr for his commit, it is correct, and I think I must be the
one to blame here with:

2007-05-23  Timothee Lecomte  <tim...@en...>

        * src/wxterminal/wxt_gui.cpp:
        * src/wxterminal/wxt_gui.h:
        Add/rewrite a few debugging messages.
        (wxt_atexit, wxt_cleanup): Simplify "persist" and exit code.
