The welcome message is necessary to distinguish the long running
filter protocol (v2) from the current one-shot filter protocol (v1).
This is becomes important if a users tries to use a v1 clean/smudge
filter with the v2 git config settings.

Oh I see, that's why we're at v2 now.
How do you distinguish between v1 and v2? Does the welcome message
need to follow a certain pattern to be recognized to make it v2+ ?

Thanks a lot for the review,
Lars

Sorry for repeating the questions (it seems I missed
a lot of the prior discussion), but I think these questions
may help future readers of the commit message,

Thanks,
Stefan
