[isabelle-dev] Presburger proof term

Hi all,

Quick question: Josef Urban noticed that the proof terms for some lemmas proved directly by "presburger" can refer to lots of other lemmas; for example, the proof of "Parity.even_mult_two_ex" directly refers to 206 lemmas.

ML {* Thm.proof_body_of @{thm Parity.even_mult_two_ex} *}

(I've attached the list.) Is that normal? Does this have anything to do with "presburger"?
