Hi, Magnus, it is the official policy to reply-to-all on this list. This has been mentioned in the past quite often, and it will be mentioned in the future, too. You actually forced me to manually look up and re-add Hannes' address. I do not appreciate having to waste my time like that. If that sounds negative, please understand that I am used to the ways of this list, and when I am annoyed by somebody not fitting in, then it is not totally _my_ mistake.

However, I will try to stay with the officially supported functionality, even if that makes msysGit slower -- Windows will never reach the performance levels of Linux anyway. Ciao, Dscho
