    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.
I fixed this.
