Bug ID: 53412
           Summary: Wine should detect existing Wine prefixes before new
                    prefix generation
           Product: Wine
           Version: 7.13
          Hardware: x86-64
                OS: Linux
            Status: UNCONFIRMED
          Severity: normal
          Priority: P2
         Component: -unknown
          Assignee: [e-mail]
          Reporter: [e-mail]
      Distribution: ---

Rough ideas how things should be:

1. don't check anything if the new command line argument is set to disable
detection of Wine prefixes
2. check .desktop files
3. check parent directory of known Wine prefixes
4. check root recursively with some exceptions
5. generate missing .desktop file(s)
6. remove unused .desktop file(s)
7. prompt user to select one Wine prefix within command line session if
multiple Wine prefixes are found
