2013-11-03-21.18.34: src/lib/prettyprint/big/src/core-prettyprint-mill-g.pkg: Spent the morning exploring all possible ways of getting newline handling wrong in group_tokens_into_lines() + flatten_lines_back_to_tokens() (a total of 35 lines of code).  src/lib/prettyprint/big/src/test/prettyprint-mill-lib-unit-test.pkg:  Added test_basic_newline_handling() with nine tests to consolidate my meager progress.
