Some Python 2.1 ideas

string.chomp() (a better name would be nice) needs to handle all of:

 - "foo\n"
 - "foo \n"
 - "foo \r\n"
 - "foo \n\r"
 - "foo"

etc. correctly, which means it should delete between zero and two bytes
(characters) from the end of the string. This is very different from
removing leading or trailing whitespace (whitespace can be significant
you know <wink>).

Before someone suggests:

   line = line[:-1]

I would note that this removes one character too many if you're reading
a file that doesn't end in a newline.
