/*
		ERRORS

	JF: this is now bogus.  We now print more standard error messages
	that try to look like everyone else's.

	We print the error message 1st, beginning in column 1.
	All ancillary info starts in column 2 on lines after the
	key error text.
	We try to print a location in logical and physical file
	just after the main error text.
	Caller then prints any appendices after that, begining all
	lines with at least 1 space.

	Optionally, we may die.
	There is no need for a trailing '\n' in your error text format
	because we supply one.

as_warn(fmt,args)  Like fprintf(stderr,fmt,args) but also call errwhere().

as_fatal(fmt,args) Like as_warn() but exit with a fatal status.
