Previously, newline: :lf was accepted but ignored. Where it should have been used was commented out code that didn't work, but unlike all other invalid values, using newline: :lf did not raise an error. This adds support for newline: :lf and :lf_newline, for consistency with newline: :cr and :cr_newline. This is basically the same as universal_newline, except that it only affects writing and not reading due to RUBY_ECONV_NEWLINE_DECORATOR_WRITE_MASK. Add tests for the File.open :newline option while here. Fixes [Bug #12436]
