Scanning visited a Ruby file first, and now a directory for the same
constant has been found. This means we are dealing with an explicit
namespace whose definition was seen first.
Registering is idempotent, and we have to keep the autoload pointing
to the file. This may run again if more directories are found later
on, no big deal.
gister_explicit_namespace(cpath)
 the existing autoload points to a file, it has to be preserved, if
t, it is fine as it is. In either case, we do not need to override.
st remember the subdirectory conforms this namespace.
space_dirs[cpath] << subdir
!cdef?(parent, cname)
rst time we find this namespace, set an autoload for it.
space_dirs[cpath(parent, cname)] << subdir
ne_autoload(parent, cname, subdir)
r whatever reason the constant that corresponds to this namespace has
ready been defined, we have to recurse.
"the namespace #{cpath(parent, cname)} already exists, descending into #{subdir}") if logger
