Description Pedro Sampaio 2019-12-11 00:30:52 UTC 
Filenames on Linux/Unix can contain backslashes. On Windows, backslashes are directory separators. Git did not use to refuse to write out tracked files with such filenames.

Does this bug apply to Fedora (or RHEL)? The commit (https://git.kernel.org/pub/scm/git/git.git/commit/?id=e1d911dd4c7b76a5a8cec0f5c8de15981e34da83) explicitly mentions mingw.
