Subject: [PATCH] Fstab: allow leading whitespace in lines with spec (#544)

The documentation does not explicitly mention this possibility, but
tooling that parses fstab actually supports this: hence, allow leading
whitespace in lines with filesystem specification.

(cherry picked from commit 6ee7170cc04c934a70cbcd1caf3e5f8821806dec)
