[peternewman]

whitespace/indent_namespace Do not indent within a namespace. [whitespace/indent_namespace] [4]

E.g.: https://github.com/OpenLightingProject/ola/blob/e8c755cdb1aba608785cce501ff5cc86f866e6d6/common/base/Init.cpp#L203-L207

Decide if/how we should fix this and remove the skip added in https://github.com/peternewman/ola/commit/2bd4368c3f2edeb1cfd8d06ac381c7414b7957d9 .
