In the case of a test data file with mismatched EOL you can add a
.gitattributes file in the containing directory that tells git to
treat the file as binary. So if this is the only issue regarding loss
of data (I suspect it isn't) and there aren't too many of these files
around, add the special case .gitattributes files.

I'm generally in favor, though, in letting the history remain the
history, i.e. that it accurately reflects the actual state at that

I'm not sure I understand the above. The bootstrap.bat file also
shows up as a problem on the Linux side as a modified file on initial
checkout, but since I don't use the file, it's just an annoyance on
the Linux side.
