A while back Byron asked if I had the patch handy for a bug in the
reader that someone noticed.  Sorry for the delay, here's the diff.
This diff also works around a bug in ObjectCenter's understanding of
declarations.  I know of a few other bugs, in the print library, but I
think they are benign.  [The fixes for those are reflected in the
version of the print code that I sent to comp.sources.unix a while
back, if anyone wants to integrate them.  (Yeah, I ought to do it.)]
