[jamming] Clean Rule: Where is it?

Jam's design is like this (simplifying, yes):
    1. decide what to do.
    2. do it.

Step 1 corresponds roughly to rule { ... }, step 2 corresponds to 
actions { ... }.

Since Clean doesn't need to decide anything, that rule can omit the rule 
{ ... } stanza. For a contrasting example, look at Object, which 
decides how to build an object file, but doesn't do anything itself.
