[Coco] winfo?

[Robert Gault]

OK, the bug was introduced when NitrOS-9 changed from cc3io to vtio. The 
source code for winfo was changed to match but not sufficiently.

Look at the following lines in the winfo.asm source:
* we got the requested device...now see if its vtio

*         ldb   #5 5 bytes to compare
          ldb   #4
          leax  vtio,pcr get addr of 'VTIO'
          leay  devname,u get addr of the driver nam
          os9   F$CmpNam see if they're the same
Note that the current source still tries to match 5 bytes (cc3io) even 
though the name is now 4 bytes long (vtio). With the change indicated 
above, the program seems to work as advertised.
