[issue22305] Documentation on deepcopy's problems is misleading

[Shailesh Hegde]

New submission from Shailesh Hegde:

https://docs.python.org//library/copy.html

"Two problems often exist with deep copy operations that don’t exist with 
shallow copy operations:

Recursive objects (compound objects that, directly or indirectly, contain a 
reference to themselves) may cause a recursive loop.
Because deep copy copies everything it may copy too much, e.g., administrative 
data structures that should be shared even between copies."

I believe the last line in above paragraph is missing a 'not' ahead of 'be 
shared'. 

It should read:
"administrative data structures that should be not shared even between copies"

Thanks.

"Because deep copy copies everything it may copy too much, e.g., administrative 
data structures that need to be shared even between copies, which may not be 
the desired goal."

helps me understand better.
