OT: Sorry, forgot to create the ticket, as I had not network connection on the train -> thanks for fixing that.

add change entry for the fix of setkomavar's postset hooks

restore missing scr@#2postset<name/var> to fix firsthead/firstfoot variables

Thanks a lot :) singlespacing is totally fine for that usecase because we don't have multi-line header/footers there. I am not sure if a specific linespread setting is required, because one who is getting that deep into it might probably configure the layer on his own, which is still possible by using mode=picture.

In the issue they also wondered because I could not remember it ever has been handled different. Didn't look up the docs, though. Okay then, we can close this. Just didn't want to branch the discussion in the other issue.
