[Bug 19072] New: Reg.exe doesn't respect help commands (appinstall)

http://bugs.winehq.org/show_bug.cgi?id=19072

Summary: Reg.exe doesn't respect help commands (appinstall)
           Product: Wine
           Version: 1.1.24
          Platform: PC
        OS/Version: Linux
            Status: NEW
          Keywords: download, source
          Severity: minor
          Priority: P2
         Component: programs
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]
        Depends on: 19071

Using 'reg delete /?'
On windows gives a helpful summary of how to use reg delete (add/query do the
same).

On wine:
austin@midna:~/wine-git/programs$ wine reg delete /?
DELETE - /? (null) 0 0 0
Error: Invalid key name

It's trying to it as a registry key!

And then, even though it shows an error, it exits with code 0 (but that's bug
bug 19071).
