In ScanDiff.print_text, the kwarg f is used to define a file-like

Thanks, applied.

As a side note, here was my workaround for getting the text output
into a variable:
class FileVar(object):
    string = u''
    def write(self, line):
        self.string += line
    def readall(self):
        return self.string

out = FileVar()
ndiff.ScanDiff(scan_a, scan_b).print_text( f=out )
text = out.readall()

There's a built-in Python module that does that; see StringIO or
cStringIO.
