I don't think emacs does this of it's own accord, fontifying is done
using regexps, a regexp is assigned to font-face. What you'd have to
do is create a hash table and keep variable names in that. as is often
my case, i know what needs to be done, but have no idea as to how to
do it? would this function be assigned to the ' ' or ';' or ','
characters? then what happens when you remove the definition of a
variable name, you'd have to make sure to remove that entry in the
hash table.
