I don't understand yet what is [NSTextStorage fontSetChanged] exactly.
But I found a workaround for my problem that the document edited flag
is set by the fontSetChanged notification while nothing was edited in
the document.
I added the following override method to my custom NSTextStorage
subclass.
- (BOOL)fixesAttributesLazily
{ return YES; }
By default, custom NSTextStorage subclasses are not lazy, but the
provided concrete subclass is lazy by default.

On Leopard, my editor application sometimes receives the
fontSetChanged notification when it was turned to the front
application. But I don't set my application as an observer of
NSFontSetChangedNotification explicitly.
The notification invokes [NSTextStorage fontSetChanged] as below
and the document edited flag is set while nothing was edited in the
document.
What is [NSTextStorage fontSetChanged]?
I can't find any documentation about [NSTextStorage fontSetChanged].
Can I neglect that notification in my NSTextStorage subclass?
Thanks,
Satoshi
