patch #6609: Using PCI parallel port cards on Windows 

* ppiwin.c (ppi_open): If the port parameter passed from the
-p option is neither lpt1/2/3, try interpreting it directly as
a base address.
* avrdude.1: Document the change.
* doc/avrdude.texi: (Ditto.)

On Win32 operating systems, the parallel ports are referred to as lpt1
through lpt3, referring to the addresses 0x378, 0x278, and 0x3BC,
respectively. If the parallel port can be accessed through a different
