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.
