Supporting both approaches would also require some feature discovery 
mechanism, or hardcodng a list of modes that support the "advanced" way, 
somewhere.

Can we agree to shelve the PREVIOUS-CHUNKS/STRING-BEFORE/etc discussion 
until someone comes with a patch that shows a convincing usage of it, in 
multiple modes?

Preferably with some performance numbers, showing a corresponding 
improvement when used together with some multi-mode package.
