[issue19217] Calling assertEquals for moderately long list takes too long

[Michael Foord]

Michael Foord added the comment:

pprint is also likely to have performance issues. I agree with Ezio that a diff consisting of more than 30(x2) lines is not likely to be directly useful anyway. 

A test for the changed behaviour would be nice.
