uniq: Fix off-by-one bug in -cD case.
When printing only duplicated lines, the first line of each set is not
printed until we encounter the second. When that happens, we need to
increment the repetition count between printing the first and the
second line, so that if we are also printing counts, we don't print the
same (pre-increment) count twice.

uniq: Fix interactive use.
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.
Explicitly ignore -d when -D is also specified.
