My reading of the later part of the thread you are basing the above is
somewhat different from your diagnosis. The funny seems to happen only
when there is a backslash-quoted glob special inside double-quotes
(e.g. "${parameter%\?*}") and the same shell does not seem to be choking
on many prefix/suffix expansion used in other test scripts.
