Subject: - move sane into State.pm
X-Git-Url: http://artulab.com/gitweb/?a=commitdiff_plain;h=549f66e157439537f4de00597b7edff30a7fe697;p=openbsd

- move sane into State.pm
- use it for every parameter to say/print
- extend it for actual printable characters, plus a hack for \n
- add confirmf for passing formats to the confirm
- adjust PkgCheck accordingly
- tweak the files test in PkgCheck to also hunt unknown files under
/var/db/pkg/somepackage
