A head scratcher, clone results in modified files (tested linux and cygwin) - .gitattributes file?

["Jason Pyeron" <jpyeron@pdinc.us>]

Does anyone have any ideas as to why this clone resulted in modified files and how to prevent it?

There is a .gitattributes in the tree, which says:

*        text=auto
*.java   text diff=java
*.html   text diff=html
*.css    text
*.js     text
*.sql    text

But even then the *.bin files full of non-ascii garbage are impacted?! But I cannot find a difference:

Deleting the .gitattributes and the checkout -- did not help. No luck deleting the file then restoring it either.

Not even git clone git://git.apache.org/commons-io.git --config core.attributesFile=/dev/null fixed it. Details below.
