There is no bug tracking system for cygwin.

I've thought about implementing one but I quail at the thought of what would
show up there given our disappointing experience with the "todo" list.

I think it is arguable whether cat should strip CRs or not.  It is not arguable
whether bash's backtick handling should treat its input as text mode.

Of course *UNIX* produces the desired result.

Anyway, I have Cc'ed the person who volunteered to be the maintainer for this
package.  Hopefully he will offer an opinion on this.

If he doesn't I'd like to survey this mailing list for the correct behavior.
If it is that cat should strip \r's then I'll drop back to the old version
unless someone wants to take the time to do more than post bug reports and
is interested in maintaining the textutils package.
