if I

git lfs track "file/with/a space in it"

all goes well until I do a push or similar, then I get

file/with/a is not a valid attribute name: .gitattributes:1

and manually adding quotes around the file name in .gitattributes doesn't help. This is pretty brutal. Is there a config option or somesuch that enables this behavior. I don't personally use spaces in file names, but some of my users do.
