[ Sorry for taking so long to get back to it.  ]

After fighting for a while with your patch (it was full of NBSP chars
and wrapped lines) and then looking at it some more, I decided to
install the patch below instead which replaces the `catch` with
a `with-demoted-errors` (and places it in the caller instead).
Maybe those errors should indeed all be replaced by silently returning
nil, but the code currently goes through the trouble of building
more precise error messages, so I felt like maybe we should preserve
that info.
