* guix/scripts/package.scm (list-installed): New procedure. * guix/scripts/home.scm (%options, show-help): Add '--list-installed'. (process-command): For 'describe' and 'list-generations', honor the 'list-installed option. (display-home-environment-generation): Add #:list-installed-regex and honor it. (list-generations): Likewise. * guix/scripts/utils.scm (pretty-print-table): New argument "left-pad". * doc/guix.texi (Invoking Guix Home): Add information and example for --list-installed flag.
