Yeah, I left it on intent. Didn't want to change box.cfg api.
Currently the keywords are parsed in log module solely so I'll
have to provide some way to make similar inside load_cfg code,
and I tried to escape it.

You know, the base idea is to configure logging via log module
solely and maybe deprecate it from box.cfg.

Anyway even if I fix it I'll do it on top of the series.
