"set edit off" breaks MI

[Vladimir Prus]

Hi, 
it looks the the "set edit off" command breaks MI completely, as the
following session illustrates

        ghost@zigzag:/tmp$ gdb a.out --i=mi2
        ~"GNU gdb 6.4-debian\n"
        [snip]
        (gdb)
        set edit off
        &"set edit off\n"
        ^done
        (gdb)
        set print static-members off
        [nothing printed at all]

After the last command, gdb does not print anything at all. 

I suspect that "set edit off" is useless in MI anyway and run into the
problem only when portring existing code, but maybe the issue should be at
least filed in issue tracker?
