Good enough, but it's error prone to have everyone write their own version of
chomp:

    def chomp(s):
        if s.endswith('\r\n'): # dos
            return s[:-2]
        if s.endswith('\n'): # unix
            return s[:-1]
        if s.endswith('\r'): # mac
            return s[:-1]
        return s # no terminator

(I actually forgot the case where the string doesn't have a line terminator the
first time I wrote it...)
