Bug-Description:

When used in contexts where word splitting and quote removal were not
performed, such as case statement word expansion, empty strings
(either literal or resulting from quoted variables that were unset or
null) were not expanded correctly, resulting in failure.

Patch (apply with `patch -p0'):
