Commons CLI incorrectly stripping leading and trailing quotes
-------------------------------------------------------------

                 Key: CLI-185
                 URL: https://issues.apache.org/jira/browse/CLI-185
             Project: Commons CLI
          Issue Type: Bug

org.apache.commons.cli.Parser.processArgs() calls Util.stripLeadingAndTrailingQuotes() for
all argument values. IMHO this is incorrect and totally broken.

It is trivial to create a simple test for this. Output:

    $ java -cp target/clitest.jar Clitest --balloo "this is a \"test\""
    Value of argument balloo is 'this is a "test'.

The argument 'balloo' should indeed keep its trailing double quote. It is what the shell gives
it, so don't try to do something clever to it.

The offending code was committed here:
    http://svn.apache.org/viewvc?view=rev&revision=129874
and has been there for more than 6 years (!). Why was this committed in the first place?

The fix is trivial, just get rid of Util.stripLeadingAndTrailingQuotes(), and consequently
avoid calling it from Parser.processArgs().
