from mount(8) code:
need_escaping[] = { ' ', '\t', '\n', '\\' };
It's used for all strings in fstab (so not for mountpoints only).

From my point of view it would be ideal to avoid fstab parsing in the
script at all.
export FSTAB_FILE=/etc/fstab.sys
for $dev in $(findmnt --fstab -o SOURCE -e -n -O no_netdev); do
fsck -T $dev
mount $dev --target-prefix $NEWROOT
done
Unfortunately mount(8) does not allow to read info about mountpoints
from alternative fstab file and it does not support --target-prefix
now. I'll add this to my TODO list.
