[Pyunit-interest] _WritelnDecorator.writeln()

[Fred L. D. Jr. <fd...@ac...>]

The _WritelnDecorator.writeln() method doesn't have a docstring, but
appears to want to allow multiple values to be passed to be written to
the output stream.  Unfortunately, it doesn't actually accept more
than one, since the underlying stream object's write() method can only
take one.  The result of passing more than one is a TypeError.

Since the unittest implementation never passes more than one, and the
signature of the current implementation is misleading, I'll suggest
that it be modified to accept at most one argument:

    def writeln(self, s=''):
        self.write(s)
        self.write('\n') # text-mode streams translate to \r\n if needed

This would avoid confusion for people attempting to extend the runner
support that uses this method.
