Putting in newlines using sed

I had no problem, in csh:

% sed 's/foo/\\
foo/g'

in sh:

$ sed 's/foo/\
> foo/g'


(don't type the prompts)  The trick is that sed will accept a newline in
one of it's patterns if it is escaped with a backslash.  The csh example
needs a second backslash to tell the shell that the command line is not
complete.
