Re: [PATCH 0/1] MR2740: winemenubuilder: Create .desktop files for programs that open URIs

[Loïc Rebmeister (＠Fox2Code)]

This is the changes I would suggest:

1. Adding a `is_protocol_banned` function and adding the `file` protocol to the blacklist.
2. Adding a registry key to disable this new behavior (`winecfg` support?)

This is the code to detect if associations are enabled:
```c
static BOOL associations_enabled(void)
{
    BOOL ret = TRUE;
    HKEY hkey;
    BYTE buf[32];
    DWORD len;

if ((hkey = open_associations_reg_key()))
    {
        len = sizeof(buf);
        if (!RegQueryValueExA(hkey, "Enable", NULL, NULL, buf, &len))
            ret = IS_OPTION_TRUE(buf[0]);
        RegCloseKey( hkey );
    }

return ret;
}
```

Maybe making a copy of it called `protocol_scheme_enabled` and using `ProtocolSheme`/`ProtocolShemeEnabled` as registry key. (Pick your favorite)

Also I saw that all registry keys related to `winemenubuilder` are missing in the official doc: https://wiki.winehq.org/Useful_Registry_Keys
