#339 Custom commands ending with "ref" are misinterpreted

[Kirill Bolshakov]

Custom commands ending with "ref" are misinterpreted. My custom class defines a number of parameterized commands like "\xxxref" and "\yyyref", that take from 1 to 3 parameters. These commands do not reference the objects defined with "\label". The editor reports the occurrences of such commands as warnings with: "Key NN is undefined"

It would be nice if either the parser was stricter, or there was a way to explicitly exclude some commands from its coverage (I would then add them to the list).
