(parse-args): Pass (list %default-options) to 'parse-command-line' and remove #:build-options? parameter. (guix-time-machine): Call 'set-build-options-from-command-line' and wrap 'cached-channel-instance' call in 'with-status-verbosity'. * doc/guix.texi (Invoking guix time-machine): Mention common build options.
