Based on the report from Dave Bodenstab.
- Turn off PnP COM device enumeration procedure if the user explicitly
specifies a protocol type with the "-t" option.
- Accept "-t auto". Now the user may entirely omit the "-t" option
in the command line, or specify "-t auto" in order to make moused
detect an appropriate protocol type automatically. In the
previous version, moused did so only if the "-t" option is absent
in the command line. ("-t auto" won't disable PnP COM device
enumeration.)
- Updated the man page.
