Hi Lennart,

In dir_cleanup() we skip if there is an item configured for the path or it
matches the glob, however we are doing it on the subpaths of currently processed
directory. This won't work in the case mentioned in the commit message. If user
wants to exclude path from cleanup entirely he has to use x /path/*, this way
all subpaths match the glob. In case of x /path/ no subpath matches such glob
and we remove them, hence checking explicitly beforehand.
Hope that makes sense.
