To test that the single quotes are considered ordinary chars when
double-quoting the parameter expansion:
$ dash -c "a=\\'a\\'; echo \"\${a%'}\""
The result is surprising and non consistent with a non double-quoted
expansion where the single-quotes act as quotes:
$ dash -c "a=a%; echo \${a%'%'}"
Additionally the manual states that the arg to substring processing is
processed as an ordinary word (as probably POSIX too).
