Is there a reason for the NULL check? instructions_ is never set to NULL.

[evy, 2014/08/09 02:26:52]

Is there a chance that code could be added in the future to set it to NULL? Or
should that never happen (it should only be set to not visible, and the code
assumes that/tests ensure that)

[sky, 2014/08/11 16:26:58]

If we start allowing it to be NULL we would have to revisit any existing code.

Done.
