According to POSIX, the moment you get to:

"${test/

the parse is undefined, and the handling of " and finding the closing
'}' are no longer specified by POSIX.  So the question becomes whether
it is smarter to follow the rules for ${test+...} or for ${test%...}
(alas, POSIX does indeed have different rules for determining how " is
treated and how '}' is found in those two setups).
