Quite a while ago, I started a branch to fix these issues.  They mostly 
work, but some (many?) of the tests in the testsuite fail because of 
issues like this.  At that point, I stopped working on the changes 
because I couldn't figure out what the other code was supposed to do.

I suppose I can try to revive the code again and see what can be done 
about these issues.
