tagnavi custom

[Carson Dyle]

Do I understand this correctly: The _first_ definition encountered for an identifier in the processing of tagnavi/tagnavi_custom defines it?

Is there a way to redefine the fmt_title for all titles without redoing everything from tagnavi in tagnavi_custom (all the A-Z stuff, and all the submenus)?  I ask because the %include of tagnavi_custom within tagnavi follows the formatting definitions, but precedes everything else.

Offhand, I don't see how to do it.  If I redefine the fmt_title lines I get the originals, which would jive with the first defined rule.  I don't care to change any of the submenus, only the title formatting and the main menu.
