53a20a543a Plug a file descriptor leak. 
When sed is asked to inline-edit files, it forgets to close the temporary
file and runs out of descriptors for long command lines (assuming you reset
kern.maxfilesperproc to something sane that's less than the number of files
passed to sed).

739de7fe1d Test 8.16 in sed.test tests the ability of a sed to handle an empty 
regular expression as the first argument to a substitute command. If
used to test a sed which (erroneously) evaluates this at translation
time rather than at execution time, the bugged sed is put into an
infinite loop. This mode of failure seems excessive. Such a failing
sed is the Free Software Foundation's sed 3.02.

The specific test was also not being executed for the BSD sed.

Both problems are now fixed.

2001590435 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/.

110c2de07c 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.
