    DELETE VARIABLES: Fix crash with FILTER.
    
    FILTER has the surprising property that it introduces a temporary
    transformation, even if proc_make_temporary_transformations_permanent()
    was previously called.  This causes a crash if the procedure implementation
    really relies on there being no temporary transformations.
    
    This commit fixes the problem in the procedures I was able to identify as
    having it, adds a comment to proc_make_temporary_transformations_permanent()
    to make it a little less likely to happen again, and adds a test
    specifically to check for regression on DELETE VARIABLES.
    
    Reported by John Darrington.
    Bug #38843.
