What's wrong with the patched file having CRLF on Windows?

The other test fails with Unix-style patch file temp.diff, unless you
use --binary switch to Patch, and with --binary it works only for
file-lf.txt. Sounds like a bug in fseek in the Windows runtime used
by MinGW.
But why should I care about these strange combinations on Windows?
Why isn't it enough that patching Unix-style files with Unix-style
patch files works (using --binary) and preserves the EOL type, and
patching DOS-style files with DOS-style patch files also works?

Why the perfectionism? If the usual cases work so well, why do we
want to insist on looking for trouble at all costs?

Because I can find no other explanation for the fact that the test
that failed for you worked for me. Maybe you should try installing
all the utilities again, make sure what Diff and what Patch runs in
each command, and see whether gnuwin32-test.cmd indeed fails for you.

all-cmd-tests.cmd just runs gnuwin32-test.cmd and
gnuwin32-lf-patchfile.cmd; I ran those two by hand, and I already
described what they did. I didn't run the shell scripts because
there's no GnuWin32 port of Bash, and because I didn't want to mix the
Diff/Patch issue with the shell behavior.

That will not be easy using the techniques you tried in sh-tests, I
suspect. Perhaps "od -c" is a good start.
