Font locking is much better in upstream Maxima's maxima.el
Hi Fermin, compare the two screenshots below:

The one that says "melpa" is what I get from the Maxima mode from MELPA; it is quite bad. The one that says "git" is what I get using the maxima.el from an upstream Maxima git-pull'ed and compiled a few days ago, and it is much better.
Do you get something similar? If not, should I try to check which other packages are interfering in on your maxima mode and maxima-font-lock? They do not affect the maxima mode from upstream...
