Fix trailing ) from interfering with extraction in keywords
In order to pre-empt any further problems from Clojure keywords, this commit inverts the previous logic: Instead of consuming everything and handling special cases, consume characters as defined by the Clojure keyword specification, and nothing else. In addition, leave string consumption as is, but—again—drop the `"`s, in order to align with the strategy of throwing away everything that is not the content of a string or a keyword, including delimiters (`"`, `:` respectively).
