libguestfs fails to parse /etc/fstab when there is a double comma after character
For example:
cat /etc/fstab | grep ",," /dev/mapper/vg00-vartmp /var/tmp xfs rw,,nodev,nosuid,noexec,relatime 0 0
How reproducible:
100%

/dev/mapper/vg00-vartmp /var/tmp xfs rw,,nodev,nosuid,noexec,relatime 0 0

This is from cu request where they cannot update a lot of VMs manually, similar issue was fixed for trailing comma.
