In my opinion, you should run
git config --global core.autocrlf false
in an RStudio terminal session. That will set the git options so they
don't mess up the md5sum values.
You should also go to the RStudio options, and in the Code section,
Saving tab, choose Serialization to be Posix (LF) and default text
encoding to be UTF-8.
Unfortunately, RStudio will still mess up the .Rproj file (see
https://github.com/rstudio/rstudio/issues/1929); there's not much you
can do about that. Just try not to commit the Windows version to the
repository if any non-Windows users are sharing it.
But do note that other people have different opinions. They argue that
files should be converted to Windows native format by git. That works
in some narrow use cases, but as soon as you try to extract a file from
git on one system and work on it on another, it breaks.
