[PATCH] builtin-help: always load_command_list() in cmd_help()

When cmd_help() is called, we always need the list of main and other
commands, not just when the list of all commands is shown. Before this
patch 'git help diff' invoked 'man gitdiff' because cmd_to_page()
thought 'diff' is not a git command.

`git help diff` no longer finds the git-diff manpage (as of tip of
next branch). I haven't tested, but I suspect

This fixed the issue for me.

Thanks!
