minifileset: note the unsupported file pattern when raising a parse error

This was useful in debugging, because I stupidly quoted it out of habit from the
command line.  This isn't a great example that clearly shows the problem, but I
don't know how to improve it.  The problem *is* obvious once a complex statement
or a clearly bogus string is used.
