dropEmptyInitThenConcatStringsSep -> concatStringSep: feature should not be empty

Browse source 
(System) features are unlikely to be empty strings, but when they
come in through structuredAttrs, they probably can.
I don't think this means we should drop them, but most likely they
will be dropped after this because next time they'll be parsed with
tokenizeString.

TODO: We should forbid empty features.
