SVN rev 214492 on 2010-10-28 22:34:49Z by jilles
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)
