Suggestion: make xbps-query --fulldeptree fail if -x is unset

[itscool900]

Becuase people tend to refer to --fulldeptree without mentioning -X. Doing this would help people intuitively understand what --fulldeptree does.

Alternatively, make it imply -X or ignore the mode outright.

--fulldeptree does nothing with -X

-x, sorry
