[Maxima-discuss] LaTeX error with imaxima

[Jinsong Z. <js...@ye...>]

Hi there,

After I updated my TeXLive distribution, imaxima gave LaTeX error with 
simple input like:

(%i1) q^2 = 1;

LaTeX error in: q^2=1
(%i2)

It seems a bug in imaxima.el, here is the patch. I don't know why it 
works with old TeXLive distribution...

$ diff -ruN maxima-5.44.0/interfaces/emacs/imaxima/imaxima.el
