* backend/pas/pas-backend-file.c
(pas_backend_file_book_view_copy): use card_sexp.
(pas_backend_file_book_view_free): same.
(vcard_matches_search): use the new pas_backend_card_sexp_match_vcard call.
(pas_backend_file_search): use card_sexp.
(pas_backend_file_process_get_book_view): same.
* backend/pas/Makefile.am (libpas_a_SOURCES): add
pas-backend-card-sexp.[ch].
