The --all and --guides commands could be combined, which wouldn't have
any impact on the output except for:
git help --all --guides --no-verbose
Listing the guide alongside that output was clearly not intended, so
let's error out here. See 002b726a400 (builtin/help.c: add
list_common_guides_help() function, 2013-04-02) for the initial
implementation.
