#html::unquote string

Similar to #html::escape, but works only on the quotation character. It's used frequently in form widget value fields. 

 [!! #define quote 'Bush Sr. "Read my lips"' !!]
 <Input type="text" name="quote" value="[!! #html::unquote quote !!]">
 [!!
  /* output:
   <Input type="text" name="quote" value="Bush Sr. &quot;Read my lips&quot;">
  */
 !!]
