How to, in a View, get list of links up against each other (concatenated without line breaks when displayed)?
Under Format click on settings and uncheck Add views row classes and uncheck Add striping (odd/even), first/last row classes

Edit:

You could use html list instead of unformated list.

Then use css to add the comas see JS Fiddle

or 

since you added the commas's manually you could display inline or float left see this answer
