[issue12759] (?P=) input for Tools/scripts/redemo.py raises unnhandled exception

Updating the patch with the test. The test checks that the re exception is 
thrown in case of the (?P=) and (?P) expressions.
It used to raise an Index exception. My only question is, the exception we 
raise now says, there invalid characters in the group name, whether in our case 
the group name is just empty.

I am working on the patch. The fix is ready. Will be delivered shortly.
It is also broken when I specify (?P) pattern

The problem with the above expression is that it does not specify a group name. 
The expression itself is not right. So, it blows up when it tries to parse the 
name. I put the check for the empty name before any processing is done.
