I think the most useful one is probably '~i|~c', which shows any package that 
is not completely uninstalled (including ones that just have configuration 
files hanging around).

I'm not sure what the third one is, but the commands I posted in a reply that 
broke threading should handle both of those well.

I will have to look into aptitude-create-state-bundle.  I'm fairly sure that's 
mostly meant when you want to save your requested actions as well.  For 
example, if the dependency resolver crashes or does something "stupid" that 
you'd like a developer to analyze (and possibly fix).
