maint: reformat code according to GNU coding standards

* cfg.mk (local-checks-to-skip): Add sc_indent.
* src/hello.c (print_help): Limit lines to 79 characters. Use spaces
instead of tabs. Use foo () instead of foo().
(parse_options): Likewise. Allow short enums on a single line.
(main): Use foo () instead of foo().
