[Bug?] patchutils: interdiff /dev/stdin ... doesn't work


Hi,

I tried running interdiff on standard input, following the example from
the interdiff manpage:

	Reversing part of a patch (and ignoring the rest):

	      filterdiff -i file.c patchfile | \
	        interdiff /dev/stdin /dev/null

The command I used was

	cvs diff -rHEAD | interdiff /dev/stdin /dev/null

and got a "/dev/stdin: No such file or directory" message from interdiff.
While I realize that there's no system-level support for /dev/stdin in
Cygwin (though bash does support it), using "-" didn't work either.  Is
this a known limitation of patchutils?
	Igor
