I tried the Johannes's script, but it seems it doesn't work well with 
the pattern of format-patch (To: <mail1>,\n   <mail2>,\n    <mailN>). 
The multilines are not well managed. I can change my script to double 
quotas (I think perl and regexp are much more powerful rather than the 
while loop though it can be less readable), if it's not ok, I let other 
git shell expert to adjust the script. I hope this thread it will be 
useful for others.
