What were you hoping or expecting to see? I'm too lazy to read
the document to figure it out.

The function texput assigns TeX properties. ?? tex at the
interactive prompt should find all TeX functions.

In particular, 

(%i10) texput ("/", texfrac) $
(%i11) texfrac (e) := concat ("\\frac{", tex1 (first (e)), "}{", tex1
(second (e)), "}") $
(%i12) tex(1-a/b);
$$1-\frac{a}{b}$$

But if the problem is just that Maxima's TeX output is outdated,
I don't know if it's really worth the trouble to redefine it ....

Hope this helps,
