Hm, does this jive with the comment about what's intended?

 * Show an option if
 *  - it's set to a non-default value OR
 *  - if the per-sb default is different from the global default

Aren't you now omitting the option if it's set in the per-sb default?

For example the "debug" option; it's off by default, globally.  The
above comment suggests that if you have overridden that global default
in the per-sb "default mount options" then it should be shown; this sort
of makes sense to me because tune2fs calls these "default mount
options," I'd expect them to behave exactly as if you had explicitly
mounted with them.

With your patch, if you've set debug as default, it no longer shows up,
