shared options and groups

 | 
						|
The principle here is to define options once, but *not* instantiate them
 | 
						|
globally. One reason being that options with action='append' can carry state
 | 
						|
between parses. pip parses general options twice internally, and shouldn't
 | 
						|
pass on state. To be consistent, all options will follow this design.
