Mea culpa. I was trusting the output of od -x to show me every byte in
the text file (even though I wasn't using mount -b). od -x didn't show
me any CRs, even though they were there.

Yes. I am now completely convinced that gnu-win32 should switch to an
all-binary-all-the-time scheme. read() should not convert CRNL to NL
(nor write() do the reverse). cat should not have implicit knowledge of
what a ^Z means (i.e., nothing under UNIX). The gnu-win32 DLL should
probably even be made recognize a ^D typed on the keyboard (not coming
down a pipe) to mean end-of-file. I'm not opposed to activating these
non-UNIX behaviors conditionally (i.e., via environment variables, mount
options, filename prefixes, etc.), but the default behavior should be
all-binary-all-the-time.
