    Keep track of match extents in occur-mode (bug#39121) · c52e26df
    Mattias Engdegård authored
    Use the `occur-target` text property to keep track of the extents of
    all matches on each line instead of just the start of the first match.
    Doing so allows us to highlight all matches when jumping to a matching
    line instead of just the first one, and it works in a more principled
    way.  It also removes compatibility problems that were introduced with
    For compatibility with code that populate their own occur-mode
    buffers, we still accept `occur-target` properties with a single
    marker as value.
