[Bug libgcj/23183] New: SimpleDateFormat fails to render '' as single quotes

["hannes at helma dot at" <gcc-bugzilla at gcc dot gnu dot org>]

When using java.text.SimpleDateFormat to render a date, single quotes encoded as
'' (see <http://java.sun.com/j2se/1.3/docs/api/java/text/SimpleDateFormat.html>)
in the format string are swallowed in the output. The following code

   sdf = new SimpleDateFormat("''yyyy-MM-dd HH:mm:ss''");
   sdf.render(new Date());

produces something like this:

   2005-08-01 18:54:05

bug should actually produce:

   '2005-08-01 18:54:05'

Interestingly, using single quotes to escape other text works as supposed, and
using '' next to escaped text also causes the single quotes to appear. Thus, 

   sdf = new SimpleDateFormat(""'' '' '''FOO''' '' ''"");
   sdf.render(new Date());

produces:

    'FOO'

while it shold produce:

   ' ' 'FOO' ' '

PS: Maybe I should have reported this bug against Classpath, but I wasn't sure
which version of classpath is used in gcj 4.0.
