Not that kpathsea should care about an Emacs variable, but _if_ the
separator is chosen with the same logic in both programs that would be
fine.  Anyway, we need a method to guess the correct separator before
calling kpsewhich, see `TeX-parse-path' and `TeX-tree-expand'.  In the
former AUCTeX looks at the structure of an environment variable, in
the latter to the value of `system-type'.
