Personally, I will never trust my repositories to core.autocrlf on cygwin.
But here's my guess as to what would happen.
On a text mount, your working files are likely to end up with \r\r\n
endings, when both cygwin and git try to add a \r when copying from the
repository. And when putting files back into the repository, even though
git removes \r, cygwin still puts it in, so your repository is still corrupt.
On a binary mount, the operation will work just fine. However, now you
have \r in a binary mount, and this will behave just as it does under
Linux - ie. few tools will be happy with your files, because they have
spurious \r. Yes, bash can be taught to ignore those \r via its
cygwin-specific igncr option, but what about other tools?

Why? If you are trying to emulate Linux, by using binary mounts, you
should not want \r in your files. And if you really insist on using text
mounts with git, you are probably better off trying the mingw build of git.
Don't work too hard, make some time for fun as well!
