2f17b7e279 Fix substitution when the regex matches the zero-length string.
There are two bugs: in the s///g case, the substitution didn't occur
at the end of the line; in the s///N case, the code didn't count
forwards along the line properly. See the sg, s3, s4, and s5 tests
in src/tools/regression/usr.bin/sed/.

13ee49d316 Correct boundary condition error in D' and P' commands when the last
line of the pattern space is empty. Don't emit spurious newline when
EOF is reached with the `N' command.

8523e9a677 Avoid checking whether each line is the last line of the file when we don't
need to know. Instead, check when we are trying to match a "$" address.
This does not change the way sed processes regular files, but makes it behave
more sensibly when used interactively.

5a3232258e Don't let the pattern space become null if the `x' command is used when the
hold space is null; some functions assume it's never null.

5953156dca Now that the pattern space contains no trailing newline, modify the `l'
command's output so it's the same as what SUSv3 specifies.

ed92199d30 Don't store newlines at the end of each line in the hold/pattern spaces,
instead add the newline when the pattern space is printed. Make the `G' and
`H' commands add a newline to the space before the data, remove bogus
addition of newline from `x' command.

ae17860040 Fix sed(1) in the case where a last line is specified and hold space is not
specified, and then the first part of the pattern space is deleted, when
there are two or more input lines, as this results in subtraction of one from
an unsigned integral value of '0'.  That bogus value is used in one case
for a loop (that will run far too many times in this case) and a function to
search for a value within a specified range of memory, however now the range
of memory is obscenely large and a segmentation fault will occur.  This is
fixed by checking for and appropriately handling a nil pattern space as if
the specified search in memory failed, as indeed it obviously will with nil
pattern space.

30ad8d9349 Correct a bug in the P function: according to 7th edition UNIX (tm), the
newline must be part of the pattern space i.e. `echo a|sed -e P' must print
a
a
and not
aa
This is consistent with gnu sed, SunOS, Ultrix (and probably others!)
