     5 Pure/tactic/lift_inst_rule: now checks for distinct parameters (could also
     6 compare with free variable names, though).  Variables in the insts are now
     7 lifted over all parameters; their index is also increased.  Type vars in
     8 the lhs variables are also increased by maxidx+1; this is essential for HOL
     9 examples to work.
