OK, good. We're on the same page then.  :-)

Well, if there is a change in ConEmu and/or MS support here, then it
all comes for free. ;-)  As I said, I'm not saying that there's
absolutely nothing that could be done to address this in Cygwin but I'm
also not saying that there is.  It is clearly a limitation that currently
has no known work-around for the specific issue without avoiding the MS
console.

Yeah, I understand the frustration and it's certainly not wrong of
you to report the problem you're seeing.  And be assured that your
report isn't ignored.  But it is something that may be difficult to
address in Cygwin's console support so  it's hard to say there's going
to be a good solution coming from Cygwin itself soon, unless there's
some developer that wants to chase this in the near-term.

I'm pretty sure that no-one actually meant to imply that you're an
"ignorant quack".  I can also say that Cygwin does support the MS
console to the extent that the MS console API allows.  That's not to
say there aren't bugs in that support or that any bugs aren't considered.
It seems you've found such a bug so I will thank you for reporting it.
And while I can't speak for any of the developers on this list, I only
wanted to impart that this issue is likely to be viewed as relatively
low priority, given the specifics of the issue and the alternatives.
You shouldn't interpret my response as one that indicates that the bug
won't be addressed or that your report isn't appreciated.  My only goal
was to try to give you the feedback you were looking for.  With some
luck, someone will find the solution to this problem even if they aren't
really looking for it and, you never know, that could happen real soon!
So I hope you find this feedback to be helpful in answering some of your
inquiries.
