patch 9.0.0912: libvterm with modifyOtherKeys level 2 does not match xterm

Browse Source 
Problem:    libvterm with modifyOtherKeys level 2 does not match xterm.
Solution:   Adjust key code escape sequences to be the same as what xterm
            sends in modifyOtherKeys level 2 mode.  Check the value of
            no_reduce_keys before using it.
