[Bucardo-general] patch request

[Grant Maxwell]

Hi

I have made some minor changes to bucardo.pm to fill the rowinfo array  
when dealing with pushdelta sync exceptions. The result is very  
efficient exception handling for
duplicate key violations. The changes were made to 4.1.0.


If anyone is interested I could post the custom exception code I'm  
using.


Could you please consider adding them to the main code. If you do you  
should surely check the code because it works without error for me  
but ... well .. you know.
I'm not familiar with using diff for patching so I did a diff of the  
two files.


Here is the diff:
