Re: Git Modifying DLL

[Jonathon Anderson <janderson@acesquality.com>]

So, I somehow didn't realize what this was when I was looking at it,
but this is the first line in our .gitattributes

* text eol=lf

It all makes sense now.

And, yea, we're using git to retain dependency relationships and bring
those files under version control so we can audit changes and go
through the full peer review process, etc
