Git has been nagging me about these files that I haven't touched being changed.
The solution was to run `git add --renormalize .`.
Apparently this needs to be done after setting up `.gitattributes`.
According to `git ls-files --eol windows/`, the .bat files were previously stored in the index with CRLF endings and will now be stored with LF endings (with .gitattributes dictating that checked out copies will use CRLF).
This reverts commit db837204da.
@ingber: "2.0.9 works fine on my x64 Ubuntu VPS, but fails as did yours on Windows x64.
Your [@iWARR] solution on Windows works fine."
@iWARR: "I want to note, that *.bat file from v2.0.8 is able provide successfully
installation for the v2.0.9 pack, as usual. Other *.bat files from v2.0.8 are fine also."
