data: protocol

[Robin Becker]

I have an outstanding request for ReportLab to allow images to be opened using 
the data: scheme. That used to be supported in python 2.7 using urllib, but in 
python 3.3 urllib2 --> urllib and at least the default urlopener doesn't support 
data:

Is there a way to use the residual legacy of the old urllib code that's now in 
urllib.URLopener to open unusual schemes? I know it can be used directly eg

urllib.request.URLopener().open('data:.........')

but that seems to leave the splitting & testing logic up to me when it logically 
belongs in some central place ie urllib.request.urlopen.
