zz: Not changing cells [left out of prev.]

[Ted Nelson <ted@xxxxxxxxxx>]

And also this (I haven't told you yet)--

I don't think I want to allow most cells to change.
 Result cells, yes (which we don't have yet.  Text cells, no.  

Text cells should be *replaceable* (with a new number
 and a "successor" relation to the other), but not changed.
 The old cell is Chugged in -d.successor, so all its connections
 are transferred to the new one.

That allows slices to make sense.  It's also necessary
 for other reasons that escape me at the moment.
