The "current working URI" is held in the global variable "cwuri", but is not 
currently exposed to scripts via a ${cwuri} variable.

It could be added fairly easily, but only if there's a convincing case for why 
it would be useful.

Yes; that's as designed.  If you want the ${filename} variable to reflect the 
URI of the current menu, then the best way would be to explicitly set it, 

  set filename http://...../next-menu
  chain -ar ${filename}
