The lsubr definition for SI:EXTEND in LSPSRC;EXTBAS seems to have
si:extend-q-overhead added into the ARG ref rather than the I ref.
Thus (SI:EXTEND VECTOR-CLASS 'X) returns #(X NIL). This Watergate
plumber was discovered only because some code was compiled in an
environment without the whitewash SI:EXTEND macro in EXTHUK.
