modify sed commands to handle non-GNU and GNU od

Another one-line fix :) tested on solaris, seems to generate identical browse_py.h
Erm thats wierd. your email (as seen in my inbox) makes it seem like
newline added AFTER the echo.
Whereas the diff in my web browser, shows line added *before* the echo?
I thought it helped draw extra attention to the fact that there was a
line-wrap continuation of a single command line, and now it is over.
I dont feel very strongly about it though.


As for why the comment change:
I think it's more helpful to people new to the code. I had a very difficult
time understanding the script, the first time I read it.
