Function get_depends was recently changed to support both normal
dependencies as reverse dependencies, via a global variable 'rule' that
equals 'show-depends' or 'show-rdepends'.

As a subsequent function will extract this function get_depends to a
separate file, the use of globals is problematic.

Instead, pass the global as an argument.

Applied to master, thanks. We really need to clean up this script to
move the "global" code into a main() function. Right now there is some
global code intermixed with sub-functions, it's horrible.

Thanks.
Yes, I agree to move the global code into main. I didn't do it in this
series to not wander off too much of the real goal, but since you have
the same idea I can do it as a follow-up later.
