1995-04-06 lcp 1995-04-06 Recoded with help from Toby to use rewriting instead of the subst rule -- the latter was too slow. But it must resort to the subst rule if the equality contains Vars.
1994-11-11 lcp 1994-11-11 Provers/hypsubst/REPEATN: deleted; using REPEAT_DETERM_N instead.
1994-11-02 lcp 1994-11-02 Provers/hypsubst: greatly simplified! No longer simulates a "eres_inst_tac" using rev_cut_eq; instead simply rotates the chosen equality to the end!
