echo and \ do not portably mix.  For that matter, shell double quotes and 
backslash escapes that are not required by POSIX do not portably mix.  To 
reliably create carriage returns in shell, you need to use printf, or else 
something like:

echo "...@" | tr '@' '\015'

Thanks.

Also we probably want to change the "only munge the first three lines" to
something like:

	format-patch --stdout |
        sed -e 's/$/Q/' |
        tr 'Q' '\015'

picking some 'Q' that we know does not appear in the text.
