I see no need to do that, since the *only* place these names exist is
in the SET command (and its friends SHOW and RESET), and SET exists only
to set system control variables. There are no user-declared SQL
variables.
The names are quite long and underscore-filled enough without adding
unnecessary prefixes, IMHO ;-)
