Thanks; I'll try it. How do I turn off the little "8" symbol by the clef?

Oh, I didn't mean to suggest that there is such an algorithm, although
it seems like it would make a cool research project. I was just using
this example to illustrate the need for the tab-understands-(-0) workaround.

That makes sense. It's a really good heuristic, actually -- I've been
rather amazed at how often simply setting the minimum fret results in
generating optimal fingerings for a passage, even for relatively complex
music.
