[developers] semi.vpm and trigger rules (and KNOPPIX+LKB)

[Emily M. Bender]

Thanks, Sanghoun.  This confirms my suspicion that the variable
types are the problem, but I thought we just decided that

(setf *variable-type-mapping* :semi)

was correct.  Should we back out of that, and have the semi
do event <> e, etc?
