Reading the kernel source it seems it only checks for exactly "--". So I
propose we support "---" in addition to "--", something like the
following (untested) patch.

diff --git a/user-params b/user-params
index 53677b5..2d41e05 100755
--- a/user-params
+++ b/user-params
@@ -14,7 +14,7 @@ for item in $(sed -e 's/[^ =]*="[^"]*[ ][^"]*"//g' \
 	# Remove trailing '?' for debconf variables set with '?='
 	var="${var%\?}"
 
-	if [ "$item" = "--" ]; then
+	if [ "$item" = "--" ] || [ "$item" = "---" ]; then
 		inuser=1
 		collect=""
 	elif [ "$inuser" ]; then
