[Distutils] Chicken and egg_info.writers problem with setup.py egg_info

[Philip Jenvey]

Say you have custom egg_info.writers defined in a project's setup.py.  
When you use the egg_info command to restore an egg-info directory  
that was previously wiped out, the project's egg_info.writers aren't  
used.

Since they aren't registered in your non-existent egg-info directory,  
they aren't picked up. Is it possible for the egg_info command do  
some boot strapping to make them work, since is has the entry_points  
string on hand?
