Hi,
+                   /* Everything is quotes is processed as a single token
*/

is quotes -> in quotes

+                   /* iterate to the closing quotes or end of the string*/

closing quotes -> closing quote

+                   /* or else ƒtsvector() will raise an error */

The character before tsvector() seems to be special.

Cheers
