Bug 619386

Description of problem:
We install JBoss as a part of RHEV-M product on Windows 2008.
Since the application is not fully 64bit, customer may want to install
it under the C:\Program Files (x86) directory, which is where 32bit
applications should be. In this scenario, if you install JBoss as
a Windows service, the service will fail to start with no error given.
The error could be found in the run.log file, and also Manually running the run batch-
C:\Program Files (x86)\RedHat\RHEVManager\jboss-eap-5.0\jboss-as\bin\run.bat
shows the following error:
\RedHat\RHEVManager\jboss-eap-5.0\jboss-as\bin\run.conf.bat was unexpected at this time.

Further debugging shows the following line in run.bat fail:
if exist "%RUN_CONF%" (
The problem is that the variable is expanded, holding (x86) which
causes the "if exist" to fail wrongly. 

How reproducible:
See my description.

Steps to Reproduce:
1. Deploy JBoss under C:\Program Files (x86)\RedHat\RHEVManager\
2. Install JBoss as a service.
3. Try to start the service.
  
Actual results:
Service won't start.

Expected results:
Service should start.

Additional info:
A fix to the run.bat:
Add the following line above the if exist line-
set RUN_CONF=%RUN_CONF:Program Files (x86)=PROGRA~2%

This would use the short form and avoid the problem.
