Jilles Tjoelker 6c38071288 sh: Only accept a '}' inside ${v+-=?...} if double-quote state matches. 
If double-quote state does not match, treat the '}' literally.

This ensures double-quote state remains the same before and after a
${v+-=?...} which helps with expand.c.

It makes things like
  ${foo+"\${bar}"}
which I have seen in the wild work as expected.

Exp-run done by:	pav (with some other sh(1) changes)
