Nope, the previous behavior leaves the database in an inconsistent state
if an operation that should modify multiple entries based on a
triggering modify fails.
The reason is that if a module returns an error the transaction is not
canceled. (Tested with a module I am writing)
The intended behavior of ldbmodify was to apply all mods that could be
successfully applied, but it did not do that correctly.
My change fixes a real problem.
If you want to modify the intended behavior I am ok, but the code right
now works correctly. Reverting will make it wrong.

Unless my change is causing problems I think a revert would be worng,
you can still add an option to have a real global transaction without
