[Bug 16845] New: Radio buttons not being checked on focus

http://bugs.winehq.org/show_bug.cgi?id=16845

Summary: Radio buttons not being checked on focus
           Product: Wine
           Version: CVS/GIT
          Platform: Other

        OS/Version: other
            Status: UNCONFIRMED
          Severity: enhancement
          Priority: P2
         Component: user32
        AssignedTo: [e-mail]
        ReportedBy: [e-mail]

Current wine behavior is to just assign the focus to the radio button, however,
Windows checks the radio button when it gets focus through the keyboard arrows.

Steps to reproduce:

1. Open putty
2. Click the Raw radio button
3. Press right arrow twice

Actual results
* Port textbox stays at 23
* Rlogin radio button is not checked

Expected results (windows behavior)
* Port textbox changes to 513 
* Rlogin radio button is checked

I'm attaching a patch that I believe fixes this, comments about it would be
appreciated.
