To export the tree(s) I have to parse the given revisions. I changed my
script like that (skip first QEMU_TRADITIONAL_REVISION):

--- xen-unstable-export.sh (revision 1090)
+++ xen-unstable-export.sh (revision 1091)
@@ -116,9 +116,9 @@
 then
        exit 1
 fi
-qemu_xen_traditional_tag=`sed -n '/^QEMU_TAG/{s@^.* @@;p;q}' Config.mk`
+qemu_xen_traditional_tag=` sed -n '/^QEMU_TRADITIONAL_REVISION/{/QEMU_TAG/d;s@^.* @@;p;q}' Config.mk `
 qemu_xen_upstream_tag=`sed -n '/^QEMU_UPSTREAM_REVISION/{s@^.* @@;p;q}' Config.mk`


I was thinking of a parsable 'make showrevisions' target, but I think thats
overdoing things.
