/* In FSFmacs there is a whole bunch of really ugly code here
to attempt to transpose the regions without using up any
- Commands which operate on the region only work if the region is active.
- Only a very small set of commands cause the region to become active:
- Those commands whose semantics are to mark an area, like mark-defun.
+ Those commands whose semantics are to mark an area, like `mark-defun'.
- The region is deactivated after each command that is executed, except that:
- "Motion" commands do not change whether the region is active or not.
See the variable `zmacs-regions'.
The same effect can be achieved using the `_' interactive specification.

+`zmacs-region-stays' is reset to nil before each command is executed.
