Let's say license_header.txt has DBeaver - Universal Database Manager^M Copyright (C) 2010-2018 Serge Rider (serge@xxxxxxxxx) and another.txt has DBeaver - Universal Database Manager Copyright (C) 2010-2018 Serge Rider (serge@xxxxxxxxx) My tool doesn't think the two pieces of txt the same because of ^M. Although my tool can do normalization internally, if git checks out files to CRLF due to core.autocrlf=true, my tool is fighting against git. git shouldn't spend time converting to CRLF which is about to be converted back to LF by my tool. That's why I set core.autocrlf=false, and ask git to normalize files to LF. So the problem is that, conversion to LF is not happening.
