Hm, with both my changed master as well as a stock 3.5, I could only get 
that document to expose editable fields when the document was in r/w 
mode and non-editable fields when the document was in r/o mode.  So not 
sure that document (or the way I inspected it) helps verify I broke 
something.

Turned out the Calc thing was independent of my changes;

"Missing initialization" fixes that.

Yeah, unit tests would have been nice.  <fill in lame excuse of choice

Indeed.  So I boldly pushed this now as 
<http://cgit.freedesktop.org/libreoffice/core/commit/?id=b9ecec7c74687ed5a9470cffb7d02e0e6e83107e> 
"Allow for editing of read-only documents" (with one small change 
compared to the earlier patch, so that r/o non-ODF documents correctly 
open as r/o, too).
