Should 'or precondition's be Short Circuited (aka Lazy Evaluation)?

Should orpreconditions be short circuited?

As it is, you cannot have pre-conditions like “only run if this table is missing OR, if it exists, check that it contains a particular record”.

e.g.

                              SELECT MAX(id)       FROM some_table      

However, if orprecondition’s were short-circuit and evaluated in the order that they appear, then once one condition evaluates to true, you do not need to continue evaluating other conditions in the or block.

It makes sense that they should.  I created an issue for it (http://liquibase.jira.com/browse/CORE-464), though it will probably not be addressed for the 2.0 release.
