Werner Koch 536841ecae * keylist.c (show_policy_url, show_keyserver_url, show_notation) 
(list_one): Use const char* for i18n string helpers.

* keygen.c (do_generate_keypair, read_parameter_file): Really
close the files.
(do_generate_keypair): Create the secret key file using safe
permissions.  Noted by Atom Smasher.
