I just tried cat >/dev/null using the cygwin CD.  I could edit the line
as expected.  I tried this from the command line, under bash, and under
/bin/sh.  All of them worked fine.

I think that if canonical mode was really broken we would have heard about
it from a numbe of different directions by now.

I also tried your test case, which worked as expected.

As a wild guess, it sounds like you may not be using the Cygwin 1.0 DLL.
