+Subject: [PATCH] util: Check for NULL string in writefile
+
+This check was there previously, but was removed in f549b757 with
+the addition of a check during parse that every rule has rspfile
+if and only if it has rspfile_content. However, this fails to
+consider the possibility of those variables coming from the edge
+or global environment. So, re-add the check.
+
+Fixes #67.
