Since cnflib.js doesn't save/restore padding areas (yet), this explains
why using scripts that use cnflib to update/modify configuration files
could result in some settings being reverted to default or blank values
unexpectedly.

Next-up: fix cnflib so it saves and restores padding areas in .cnf files.
