When I do `facemenu-set-invisible' on a region, subsequently inserted
text is invisible.  I have hardly an opinion on that because I didn't
even know about this function before.  But I think inserted text should
go before the invisible text if `point' was at the beginning and after
invisible text if `point' was at the end of the region.

I agree that would be bad.  Is that the way it behaves now when I set
the rear-nonsticky property?

In general you're right.  I was referring to the effect immediately
after executing that command.

That would be fine.
