f020c7fa88 Fix a bug in sed(1)'s "s" command wherein if an escape ("\" character) 
was initiated at the last character of the line buffer, the Wrong
Thing was done and sed barfed by interpreting the following NUL byte
as a digit.  Instead, pull up the next buffer and record that the "\"
was last seen.

efaed24f7d Fix an ages-old bug in sed(1), which resulted in the absolutely valid 
substitution expressions in the form `s,[fooexp],[barexp],;...' treated
as invalid when the third `,' is (_POSIX2_LINE_MAX * N)-th character in
the line.

13ede3c083 Terminate our output string correctly if we've got 
an ``a'' command that has an escaped newline on the
last line of the last script that we're processing.

This fixes exmh2/scripts/build when /etc/malloc.conf -> AJ

49e6559936 Yet^2 another fix for the line continuation bug. 
The fundamental problem with the original code is that it accesses
p[-2] which is one before the beginning of the input buffer for
empty lines.  rev.1.6 just moved the problem from failures when
p[-2] happens to be '\\' to failures when it happens to be '\0'.
rev.1.5 was confused about the trailing newline and other things.

I went back to rev.1.5 and fixed it.  The result is the same as
Keith Bostic's final version in PR 1356 except it loses more
gracefully for excessively long input lines.
