Do you mean the Quilt workflow? From a quick look:

https://lists.nongnu.org/archive/html/quilt-dev/2008-01/msg00000.html
https://bugs.debian.org/cgi-bin/bugreport.cgi?bug=749069

Is that the issue? I am surprised it loses that information...

Other script calls do not do that, so I would prefer to avoid it. But
I can take it temporarily to help you (until we are in mainline, if I
understand correctly the issue), but I would prefer to have a comment
nearby it justifying the workaround and explaining when we can remove
it.

Cheers,
