The problem seems to be that the binding is declared as:

M-~S-9

rather than:

M-9

If I change it to the latter, then I can unbind it. So the unbinding 
routine is failing to deal with the 'ignore' case. I.e., M-9 does not 
match M-~S-9, so it thinks there's nothing to unbind. And it shows as 
just M-9 in Tools> Preferences, and that's what it writes to the 
user.bind file.

It seems to me we should just go ahead and unbind in that case, whether 
the 'ignore' part matches or not. Thoughts?
