The underlying issue here is the one discussed in the thread "Little
problem while converting from bash" back on May 12 (e.g. users/8822).
There was also a lengthy thread "zsh and line breaks" in April 2004
on the zsh-workers list which partly explains how we got to where we
are now.

I think the answer is that $_comp_setup in compinit should contain

	local IFS=$'\r'"$IFS"

The question is whether it would hurt to treat CR as whitespace in
completion on other platforms -- if it would, then we need to make
that conditional on Cygwin, somehow.
