+Fix to_tsquery() and websearch_to_tsquery() to properly parse certain discarded tokens in quotes (Alexander Korotkov)
+
+
+Certain discarded tokens, like underscore, caused the output of these functions to produce incorrect tsquery output, e.g., websearch_to_tsquery('"pg_class pg"') used to output '( pg & class )
+<-> pg',but now outputs 'pg <-> class <-> pg'.

-Make websearch_to_tsquery() parse text in quotes as a single token (Alexander Korotkov)
+Fix websearch_to_tsquery() to properly parse multiple adjacent discarded tokens in quotes (Alexander Korotkov)
-DETAILS? ALREADY CHANGED ABOVE.
+Previously, quoted text that contained multiple adjacent discarded tokens were treated as multiple tokens, causing incorrect tsquery output, e.g., websearch_to_tsquery('"aaa: bbb"') used to output
+'aaa <2> bbb', but now outputs 'aaa <-> bbb'.
