imaxima in emacs



Hello,

I copied the new imaxima.el I obtained from Yasuaki Honda over the old one 
included in the imaxima-5.16.3 distribution and it seems to be working fine now. 
The OS was opensuse 10.3,
latex: Version 3.141592-1.40.3 (Web2C 7.5.6)
gs: ESP Ghostscript 8.15 (2006-04-19)


I noticed there is not yet support for the derivabbrev : true 
in emacs/imaxima, which makes dy/dx look like y_x? Or is it possible to
get this working somehow?

Regards,
Nijso
