+Subject: [PATCH] Don't save the original name and timestamp
+
+Explictly pass -n option to not save the original name and timestamp for
+improving reproducibility. In our test, always set mantype to man, but
+the output like erb.1.gz is not stable, sometimes, "last modified: xxx"
+is added to the file type, which make the build not reproducible.
