Reverting changes to stringifyList (#4249)

Browse Source 
I (Flibbles) changed it so that lists generated by stringifyList
would always be compatible with a filter parser, but since lists
are not, and never will be, a subset of filters, there isn't a
point.

More importantly, wrapping negative numbers like "-7" in brackets
would mess up some math stuff.
