As I've mentioned before, that isn't the purpose of the rules= option.
Once I've merged the rules= and color= options, I can re-use the
rules= option to read rules from a file (but I don't think that you
can specify a default directory for a file option).
Beyond that, it may be worth replacing colour=rules with a flag. Or
even a completely separate r.colors.rules module (I think I've already
expressed my opinions on having an interactive mode in a module which
is otherwise non-interactive).
For now, I'm going to wait to see if any issues arise from the most
recent round of changes.

I'll look into it either when I eventually deal with the rules=/color=
issue (probably 7.x) or when another "modifier" actually gets added.
