Phil:  OK, I see what you're saying now.

What I was talking about was a duplicate echo.  Not the normal echoing of
characters which you can turn on and off with stty, but a *second* copy of
the line you just typed which is echoed immediately after pressing the ENTER
key.

cat > file
this is a test. (ENTER pressed here)

cat is broken in the 5/23 release, fixed in the 1/16 and 6/10 releases (I
don't know why).

Regarding those "trace thingies":

The problem is that I'm experimenting with different versions of the
cygwin1.dll to see if I can find one which fixes some of the more serious
bugs without introducing new bugs.  For example, the 5/23 dll fixes the
"find command broken across mounts" bug but breaks cat in the process.  I
guess that's what's meant by a "stable" release -- a release which
introduces very few new bugs of its own while fixing a substantial number of
the bugs in previous releases.  

If I'm experimenting with every version of the dll after 5/23, trying to
find one which fixes the problems I'm experiencing, it's a real pain to have
to unpack the inst archive, too.  I was hoping someone could tell me: "The
version released on, e.g. 6/10, fixes most of the reported bugs that have
been fixed so far and ***has not been reported to have introduced any
serious new bugs***".  Then I could grab that version of the dll and the
inst archive and spend the time to install them with reasonable confidence
that I'll have a working system when I'm done ("working" means "with all the
goodies which have worked in the past but without major new bugs").
