    Returns list of tuples (fragment, style), where fragment is a part of text
    between two brace-delimited override sequences, and style is the computed
    styling of the fragment, ie. the original style modified by all override
    sequences before the fragment.
    
    Newline and non-breakable space overrides are left as-is.
