Advice + proposals regarding automodule naming

[Brian Fox]

Hi Mark,

We maintain a separate database of the complete list of all files
(recursively unpacked and hashed) that drives our Lifecycle suite of
products, so the count of pom.properties came from here. My guess is that
since the internal maven isn't likely a full mirror, there's just a sample
skew there.
