[plt-scheme] "procedure ..." in mzscheme error messages

I don't think the error-print width affects that. A location-based name
is generated at compile time, and it uses some arbitrarily chosen width
--- something like 30 characters. The 30-character cut-off often has
the nice effect of keeping a machine-specific path out of bytecode,
though it's a hack for that goal.

To support backtraces, there's a more complete and portable path stored
with procedures (which was added long after the procedure-name
support). So, I could change the way that the procedure name is
generated and build it on demand from the more complete path, instead
of keeping just 30 characters of the original filename. But then this
needs to be generalized to work with other forms, such as `class'...

I'll put it on my list as something to clean up, but it probably won't
happen soon.
