I find this statement outrageously offending. Why do you assume the programmer is a "she"? It might as well be a "he". Or it might as well not want to be associated with any gender (consider a transexual, asexual, or an alien from Mars).

I think s/h/it is the correct pronoun to use to cover all those cases.

(yes, it's /s. When I see "she" used to imply the author is oh, so progressive and non-sexist, I resort to sarcasm).
