/*
ERRORS
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.
