Make --color attributes mergeable

Browse Source 
So you can override the colors and still have the text attributes

    # Default colors and attributes
    fzf

    export FZF_DEFAULT_OPTS='--color hl👎underline,hl+👎underline:reverse'

    # Default colors with underline+reverse attributes
    fzf

    # Different colors with underline+reverse attributes
    fzf --color hl:176,hl+:177
