teeinput

{HOL,ZF}/indrule/quant_induct: replaced ssubst in eresolve_tac by
separate call to hyp_subst_tac. This avoids substituting in x=f(x)

{HOL,ZF}/indrule/ind_tac: now tries resolve_tac [refl]. This handles
trivial equalities such as x=a.

{HOL,ZF}/intr_elim/intro_tacsf_tac: now calls assume_tac last, to try refl
before any equality assumptions
