It could be done that way, but it isn't done that way now, and I
have no intention of changing it. mawk also fails:
$ mawk 'BEGIN { RS = "[x" }'
mawk: run time error: regular expression compile failed (bad class -- [], [^]
or [)
[x
FILENAME="" FNR=0 NR=0
The lesson is to set RS with a valid regexp.
