help: correct logic error in combining --all and --guides
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.
