Which was a bug in the GUI for offering it in the first place, because
it basically set the text-mode mount flag on every single directory,
including /bin, which is counterproductive.

But you didn't need the setup.exe radio button to get the same effect,
instead, just change your mounts manually (/etc/fstab) to set the
text-mode mount flag on the subset of directories where it matters to you.

Then tell bash that you want it to ignore CR (set -o igncr, or set
SHELLOPTS in the environment before invoking bash).

That's why we don't recommend text-mode mounts for cygwin-owned
directories.  dos2unix can also do some smart conversions (it has smarts
to avoid corrupting binary files while still converting text files).
