This PR resolves issue with changed field set in the case where the top level (master) field ("_") is not requested by the client, but the master field callback causes all fields to be marked as updated, rather than only those fields that have actually been modified. The example below shows how the code works with this PR: the PV structure contains 4 fields, with the field 'z' the only one not being updated on the server side, and this is indicated correctly using pvmonitor and printing only fields that changed (after the initial update):
Without this fix, all fields would be marked as updated.
