parser: Fix parameter expansion inside inner double quotes
The parsing of parameter expansion inside inner double quotes
breaks because we never look for ENDVAR while innerdq is true.
echo "${x#"${x+''}"''}
This patch fixes it by pushing the syntax stack if innerdq is
true and we enter a new parameter expansion.
This patch also fixes a corner case where a bad substitution error
occurs within arithmetic expansion.
