It's been suggested before that the style files have some sort of  
#include directive.

As an example.  We have a style called 'pedestrian'.  The style rules  
file ./pedestrian/points would have a line at the top that said:

#include ../default/points

This would mean that the file ./pedestrian/points would include all  
the default points style rules.

Below the #include directive in the ./pedestrian/points file would be:
a) additional style rules not present in ../default/points
b) over-rides (i.e. style rules that match the same OSM objects as  
../default/points, but do something different)

This would mean you could keep your own styles fully up to date with  
changes to the default style, and save you re-writing lots of rules  
that you don't want to change from the default.
