Output line too long.

- the man page mentions no line length limit
- the output error message doesn't have the name of the program (sed) in it
- the error message doesn't say what the limit is, e.g.
sed: output line longer than 10240 bytes
Sed also won't preserve binary files (try running /vmunix through a
substitution that does nothing -- you don't get out what you put in),
though we've come to expect that with most Unix utilities, haven't we?
