"Latin-1" is the official name and the one used internally by Python,
so it would be good to have the test suite and Python code in general
to use that variant of the name (just as "utf-8" is preferred over
"utf8").

Instead of adding more aliases to the C code, please change the
encoding names in the stdlib and test suite.
