Moving from developing on MAC to Windows and hitting command:warning: LF will be replaced by CRLF in src/setup.cfg.

Throws this error.

Any ideas how to overcome?

Bump2version no longer modifies line-ending style as of #59.

[Cito]

This happens even when commit=false. I think bump2version should not change the kind of line endings. If a file uses LFs, it should still have LFs after being processed, even on Windows.
