R David Murray 7567865867 #20815: small readability improvements in ipaddress tests. 
Patch by Michel Albert.  We don't normally do patches that just tweak
whitespace, but ipaddress is relatively new and the package maintainers
approved the patch.

# One big change in ipaddress over the original ipaddr module is
# error reporting that tries to assume users *don't know the rules*
# for what constitutes an RFC compliant IP address
# Ensuring these errors are emitted correctly in all relevant cases
# meant moving to a more systematic test structure that allows the
# test structure to map more directly to the module structure
# Note that if the constructors are refactored so that addresses with
# multiple problems get classified differently, that's OK - just
# move the affected examples to the newly appropriate test case.
# There is some duplication between the original relatively ad hoc
# test suite and the new systematic tests. While some redundancy in
# testing is considered preferable to accidentally deleting a valid
# test, the original test suite will likely be reduced over time as
# redundant tests are identified.
