A question regarding cStringIO.StringIO(): is there a way to do get
getvalue() to return all the bytes after the current file position
(not before)? For example
buf = cStringIO.StringIO()
buf.write("foo bar")
buf.seek(3)
buf.getvalue(True) # the True argument means
# to return the bytes up
# to the current file position
That returns 'foo'. Is there a way to get it to return ' bar'?
