Filter name tokens are strings containing a mix of letters, digits,
periods, underscores, or hyphens; the lexical analyzer and parser don't
care where the periods are, it just hands the string to
"dfilter_lookup_token()", which looks it up in a tree.

I.e., the significance of "." in filter name tokens is conventional, not
syntactical; it's not assumed by the filter code to separate components
of names.
