[Zope] Disabling "Expand macros when editing"

[Damon Butler]

Hi,

We just recently upgraded from various installations of Zope 2.7/2.9 to 
Zope 2.10. The page template feature "Expand macros when editing" is 
causing us major headaches. It is checked on by default, and as a 
result, the instant we wish to view the source code of any ZPT, it has 
been mangled into "expanded" form before we have a chance to do anything 
to it.

THIS IS BAD!

How can we turn this feature off globally? Right now, it is flatly 
impossible for us to edit most of our ZPTs because the instant we even 
look at them they are mangled. We can't even uncheck the option without 
saving the mangled version.

It's Catch-22 of the worst sort. Please help!
