That would be a great improvement I think, although if it sometimes ends up
suggesting the wrong line then that will cause some extra confusion.

OK. Having the metafont error suggest possible causes might be good (and
probably removing some of the slovakian variable-names stuff which doesn't
help anyone except maybe you), so that the error makes more sense to a normal
user.

OK, well for now the best hing is to use these examples I have
(unfortunately) produced to demonstrate likely problems and solution, and
diagnostics. Your reply explaining how you found my errors is exactly what
people need in order to learn therion-fu, so thanx very much for that. More
for someone to put in the FAQ.

MartinS can you do that again (with the pictures and everything) and I'll
tidy it up? I'll get round to it eventually but I have survey-drawing and
work deadlines this month _and_ my engine blew up on christmas day so I have
to spend a lot of time under the car this month too, so time is limited.
