I agree that it's confusing. More confusion:
sed's man page does not mention the -b option, although sed --help does.
grep also strips CRs, but has option -U to suppress this behavior.
awk also strips CRs. I could not find an awk option to suppress this.
IMHO it would be preferable to replace this confusing state and align 
these tools with Cygwin's philosophy to work like GNU/Linux.

The standard response to issues dealing with CRLF files is to point the
user to dos2unix and text mode mounts. This should be adequate without
the hidden behavior of sed/grep/awk and probably others.

Respectfully submitted,
