[tor-commits] [stem/master] Only show newly added descriptor lines once

commit be11d89bf20d8c46bbc463b78fbca217bb8d4d42

    Only show newly added descriptor lines once
    
    Microdescriptors added a new field and our tests are notifying us about it.
    This is all well and good, but since it notifies for *every* line it drowns out
    the rest of our test output. We only need one example of the line so
    suppressing the rest.
