Ævar Arnfjörð Bjarmason 1ed4bef6b4 help: correct logic error in combining --all and --config ...

Fix a bug in the --config option that's been there ever since its
introduction in 3ac68a93fd (help: add --config to list all available
config, 2018-05-26). Die when --all and --config are combined,
combining them doesn't make sense.

The code for the --config option when combined with an earlier
refactoring done to support the --guide option in
65f98358c0 (builtin/help.c: add --guide option, 2013-04-02) would
cause us to take the "--all" branch early and ignore the --config
option.

Let's instead list these as incompatible, both in the synopsis and
help output, and enforce it in the code itself.
