/* GTK on OS X is currently (February 2012) setting both
the Meta and Mod2 bits in the event modifier state if
the Command key is down.
gtk_accel_groups_activate() does not invoke any of the logic
that gtk_window_activate_key() will that sorts out that stupid
state of affairs, and as a result it fails to find a match
for the key event and the current set of accelerators.
to fix this, if the meta bit is set, remove the mod2 bit
from the modifier. this assumes that our bindings use Primary
which will have set the meta bit in the accelerator entry.
