Yo, this is definitely a bummer - even for datastructures, populating
the data subpatch trips the dirty flag, which is often unwanted when
the DS are just transient bits saved via a different mechanism than
writing to the patch file (like SSSAD).

But, it seems like a [clean( message might inadvertently cause one to
lose work, e.g., if you make a wanted, permanent change, tripping the
dirty flag, and then run an operation which sends a [clean( message,
you would not be able to distinguish which change was meant to be
permanent and which was transient.

So, a different idea might be a message which can temporarily or
permanently toggle detection of changes in a patch or subpatch.  This
way, one could turn off dirty-detection, make a change using
[donecanvasdialog(, and turn it back on again.  One could then
effectively specify which operations are meant to be saved and which
are not.

To complete this idea, though, we also need a [savebang] object to
fire before the patch is saved to restore the patch to its original
state (clearing subpatches, restoring GOP size, etc.).  I know this
can be built with [tot] but it's not reliable (I have a [savebang]
abstraction in sfruit/ which I've tried to use for this purpose - it
only works half the time or so).
