Bug#974888: growlight: Reproducibly segfaults on pressing F1

[Nick Black]

I actually seem to be seeing a variety of segfaults using this package
(1.2.18-3 atop libnotcurses1 2.0.4+dfsg.1-1),
problems that one normally certainly doesn't see. It's possible that
there's a deep rot in how I assembled this
binary package. Either way, I'll have things resolved by tomorrow's end.
I'm sorry for the negative first impression!
