Re: Zsh 4.0.4 and Emacs 21.1 in Windows XP

[Gary Oberbrunner <garyo@genarts.com>]

I don't know if anyone cares, but I just created this patch, which 
*does* work for me.  Nothing else I tried seemed to do it.  It adds a 
new option, emacscygwinhack, which deletes any CR at the end of a line 
(it works analogously to sunkeyboardhack).

Feel free to come up with a better name for it if you find it at all 
useful.  Andrej: I tried everything I could with CYGWIN, and had no luck 
at all.  Maybe it's just me though.
