As I said before, I've stopped using a physical DEC VT100 around 1990,
and gained the ability to extend my terminal to a bit more that 80
columns. And even the VT100 could be coerced into using a 132 column mode...

Adhering to a convention can be good, but common sense must apply first.
Splitting an assignment is visually annoying and in that case, it
doesn't make much sense. I'll happily take a line that goes beyond 80
cols, and if you really wanted to stay within boundaries, how about
turning "num_parent_irqs" something shorter?

Thanks,
