Output a line as soon as it is possible to determine that it will have to be output. For the basic case, this means output each line as it is read unless it is identical to the previous one. For the -d case, it means output the first instance as soon as the second is read, unless the -c option was also given. The -D and -u cases were already fine. Add test cases for interactive use with no options and with -d. Sponsored by: Klara, Inc.
