Bash bug on continuation lines with CRLF?

Hi,
I think I've found a bug with CRLF handling, this time in the bash
shell port: "continuation lines" in shell scripts (i.e. command
arguments ending with a "\" character to be continued on the next line
in the script) causes parse errors.
Here's a simple script for reproducing what I believe is a bug (using
^M to signify ASCII character \015):
-->8-[cut here]-->8--->8--->8--->8--->8--->8--->8-
#!/bin/bash^M
^M
echo "foo" "bar"^M
^M
echo "foo" \^M
"bar"^M
^M
-->8-[cut here]-->8--->8--->8--->8--->8--->8--->8-
Running this under cygwin v1.1.4 results in this output:
$ ./test.sh
foo bar
foo
./test.sh: bar: command not found
$
Removing the CRs will of course give us:
$ ./test.sh
foo bar
foo bar
$
I couldn't find any other reports on this exact problem in the
mailinglist archives, but I might have overlooked it. If so, please be
gentle. :^}
I've attached the output of cygcheck below. Let me know if any other
information is needed.
Regards,
Morten
