OK, from a maintenance (e.g. -longterm) POV, that may be
a problematic patch hunk, however some people
consider (extra) forward declarations of function signatures to be a code smell.
And in this case this function clearly is infrastructure material for
several card-specific patch functions later on, thus one could
probably(?) argue that it should be at the top and not "somewhere in between"
all the patches.

But I can certainly change the patch to use whichever is the more favourable way.

Thanks!
