I'm unaware of a method that summarizes merge details per variable.
However, on multiple occasions, I've needed such a method, so I second
your request!

In other words: I have two datasets with a number of overlapping variables and I want to find out how often, for each variable, a missing observation in the master was updated with a non-missing observation in the using dataset.  Likewise, how often were observations in the master no updated because of a non-missing conflict.  Basically, this would be similar to the current merge results table, but on a variable-by-variable basis rather than based on the dataset as a whole.
