What is the point of this PR?

To correct the file permissions of repo content...

[e-kwsm]

Yes, the files have execute permission wrongly.

[DennisHeimbigner]

Does having execute permission set cause any failures or problems?

[alippai]

I don't think it causes any problems. I can compare this to having a dozen unused empty files checked in a repo. It won't cause any problems, but also it's clear it shouldn't be there. This is true for the extra permissions too (git default permissions are 644, you have explicit change setting it to 755).

@e-kwsm seems like this PR is awaiting you to sign the CLA, if you don't wish to do that, I'd be happy to submit this change as a PR, if you want.

Honestly, there's no IP here, so the CLA isn't really necessary. @WardF feel free to merge without it.
