Well, that was my first response. But that hardwires
"next" as the alt text.  If you are only working in
English, or you don't care about the alt text,
then that's fine.  I sought to 
preserve the beautiful localization service that
the existing gentext.nav.next template provides
for the alt text.

I guess I should have seen that one coming.  8^)

I filed a feature request and assigned it to myself.
I assume this should be handled in a manner similar to
the option for admonition graphics, right?
