The patch is already in the GDB repository.

Please do, but this should be done so as not to disable any "set
height" commands in the init files that GDB reads when it starts.
Otherwise users who do want to set that option for some reason will
crucify us.  If this becomes tricky, the only reasonable way out might
be a user option which defaults to off.

Thanks.
