+Subject: [PATCH] libmount: trim leading commas from each options string
+
+Fixes a bug in option string parsing wherein a line such as:
+
+  ro,relatime,,nosuid,nodev
+
+Will be seen as only the tokens "ro" and "relatime" after the parser
+encounters a zero length (and erroneously declared NULL) option.
