This file is being generated as a result of 8381d0d

This was done to make the sed call work on Macs. I have gsed aliased to sed on my Mac, so I didn't hit whatever the problem was on Macs myself when setting this up. I'm not sure if/how one would call sed to not create a backup file, because sed has always been a mystery to me. =)

maybe we just rm the .backup file once we are done?

[dibyom]

or just add it to the .gitignore :)

heehee. =)

I believe this issue was solved in #5418 and can be closed now, thanks @JeromeJu!

Yup, closing.
