*Every capability*.

Please look at binary format of terminfo carefully.

Both termcap and source format of terminfo use "key=value" format,
so different vendors can add new capability independently, if their
key names don't conflict.

But binary format of terminfo doesn't have key field.
So, everytime one vendor add a new capability, that capability
conflicts with capabilities of all other vendors with that offset.
Such conflicts actually happened on commercial Unix vendors... ;-<
