I experimented a lot with mode-local variables and functions but finally
gave it up.

Currently, I think a mode_hook is an efficient way to achieve this. All
well-behaved modes call a <modename>_mode_hook(), so nothing new is needed.

OTOH, jed 99.17 provides an extensible mode_info, while the old modeinfo
was restricted to 

     fold_info,			       %  folding.sl: beg\rend\r\beg1\r\end1
     dabbrev_word_chars,		       %  word chars for dabbrev mode
     init_mode_menu,
     chglog_get_item,
     use_dfa_syntax,

See modeinfo.sl. I did not test it, but can imagine to extend 
mark_word() to use mode_get_mode_info("word_chars").
