After taking a pause I see that you are right. There are problems with 
my patch. I was somehow assuming that the buffer local value of 
shell-file-name could not be propagated further. I just thought about 
the command you send to the shell, but you can of course do other things.

However an easy way to fix this would be to have a new variable, 
buffer-shell-file-name, that is always buffer local and with a global 
value that is always nil. Setting this whenever starting a shell process 
and checking for this in w32-shell-dos-semantics would be enough.

The reason I prefer this way is that there might more problems with 
this. Because of this I believe that it would be a buffer local variable 
holding the value that shell-file-name had when the buffer was setup.
