New Revision: 200442
URL: http://svn.freebsd.org/changeset/base/200442
Log:
Don't read the newline character to line buffer because lines are passed
to wcscoll(3). Newline characters could cause incorrect results when
comparing lines.
Also, if an input line didn't contain a newline character, it was
omitted from the output. According to my interpretation, SUSv3 requires
that the newline is always printed.
Add regression tests for the cases. [1]
