The documentation currently indicates that enable-checks anddisabled-checks can't be combined for gocritic. That is however notaccurate: as per InferEnabledChecks in the gocritic wrapper,* if enable-all is set, all available checks are added to the set of  enabled checks* otherwise, unless disable-all is set, the default checks are added  to the set of enabled checks* then the checks corresponding to each enabled tag are added* then all enabled checks are added (with a warning if a check is  enabled multiple times)* then the checks corresponding to each disabled tag are removed* finally, all disabled checks are removed (with a warning if a check  wasn't enabled)Using both enabled-checks and disabled-checks is useful when keepingthe default set of checks as reference.This adjusts the documentation to match the implementation.Signed-off-by: Stephen Kitt <skitt@redhat.com>
