An equivalent definition, and somewhat shorter, is, I think,

sa2 (name, ex) := printf (false, "~%\\sa{~a}{~a}", name, tex1 (ex));

making use of built-in tex1 to produce a TeX string for ex, and ~% in
printf to produce a newline.

By the way, is this something related to pedagogy? I forget whether
you said anything about that already.

Hope this helps,
