Can't mvbak on a file with an empty space

[BarbzYHOOL]

mvbak "my test file"
mv: target ‘file.20190225_155546.bak’ is not a directory

I also get other errors:

mvbak eee\ \(autre\ copie\)
autre: command not found
- (line 1):

^
in command substitution
    called on line -1 of file -

from sourcing file -

mv: cannot stat ‘eee’: No such file or directory

I tried to fix it by adding quotes to some variables, but it still doesn't work

Usage:
  mvbak SOURCE...

Need some guidance here :'( @bobthecow

Ok I found the solution, but which one is better?

function mvbak --description 'Rename files to make a backup copies'
  __bak mvbak mv '$argv'
end

function mvbak --description 'Rename files to make a backup copies'
  __bak mvbak mv \"$argv\"
end

The second one looks better to me (cause it's clear)

Also if you have a dir called "foo bar/" it will fail to remove the "/"

__mv_bak_name works fine but the overall program does not:

mvbak pa\ pa\ pa/                                                            
mv: cannot move ‘pa pa pa/’ to a subdirectory of itself, ‘pa pa pa/.20190225_162111.bak’
