I'm still planning to add better support for reporting where a
message is coming from, and I was going to call my description of
that a "message context".  But I can call it an "origin" or
"location" instead.

I was planning to put reporting of errors to the listing file at
a layer below the reporting to the callback.  Obviously this
doesn't mesh with your plans.  I'll have to do something else,
then; perhaps the callback is responsible for deciding what, if
any, errors should be reported to the listing file.

It sounds reasonable, but I don't have a good idea of how the GUI
code works so I'm not really a good person to say.
