Perhaps, but

	- error_util doesn't provide any way to distinguish between
	  the ordinary error message and the extended stuff that
	  is output with --verbose-errors.  This is a useful distinction
	  to make, and the current code does that by using "\t"
	  rather than "file:nnn:  " as the prefix for the extended stuff.

	- I was just making the minimal fix to correct the misleading
	  error message.
